Here is NFL.coms Guard and Center weigh ins.

Jon Asamoah

• Height: 6'4"
• Weight: 305 lbs.
• Arm Length: 33 in.
• Hand Size: 10 1/8 in.
• College: Illinois
• Conference: Big 10

Asamoah is a three year starter for the Illini and has the foot agility, body control, and intelligence to play on either side of the center. He is exceptionally quick into his blocks and has the ability to make reach blocks on opponents playing on his edge. He is a good knee bender but will allow his pads to get a bit high at times and will overextend at times causing him to struggle when having to recover and right himself against good counter moves. He is more finesse than powerful or explosive but does show good lower body strength to hunker down and stop the bull rush.

Zane Beadles

• Height: 6'4"
• Weight: 310 lbs.
• Arm Length: 33 3/4 in.
• Hand Size: 9 3/4 in.
• College: Utah
• Conference: Mountain West

Beadles is a four-year starter that played guard in 2006 but has been Utah’s starting left tackle for the past three years. He will require some re-tooling becuase he is used to playing out of a two point stance and needs to line up with a hand on the ground in the NFL. He is an adequate athlete that would struggle with the kind of speed coming off the edge in the NFL and needs to move back inside to guard. He understands angles and blocking schemes and should be a quick study at the next level.

Dorian Brooks

• Height: 6'2"
• Weight: 306 lbs.
• Arm Length: 33 3/4 in.
• Hand Size: 10 in.
• College: James Madison
• Conference: Colonial

No scouting info.

Jeff Byers

• Height: 6'3"
• Weight: 301 lbs.
• Arm Length: 33 1/8 in.
• Hand Size: 9 1/2 in.
• College: Southern Cal
• Conference: Pac 10

Byers has played a lot of football at USC and has started at both guard and center, which will be a plus at the next level in that he has position versatility. He is a tough, try-hard type of blocker who will fight and scratch to try and get the job done. He is not always efficient with his footwork and will take too many steps when coming out on the pull or when releasing to get out to the second level. He is quick to recognize stunts and games up front and will make the quick decision without hesitation. He does a good job of getting a fit with his hands and has enough hand pop and strength to control his opponent's pads and steer him away from the lane. He is the kind of lineman coaches love but has too many holes, physically, to be a sure-fire player over the long term.

Brandon Carter

• Height: 6'6"
• Weight: 329 lbs.
• Arm Length: 33 1/2 in.
• Hand Size: 10 5/8 in.
• College: Texas Tech
• Conference: Big 12

Carter is a three-year starter at guard for the Red Raiders and has played a lot of football over the years. He will show some nastiness in his blocks but sometimes lets it get personal and has been known to get flagged for penalties at inopportune times. He is a mauler and a brawler as a blocker that can smother opponents once he gets his hands on them but will struggle when reacting to movement or when in space. Carter is probably too limited, athletically, to be a top line starter in the NFL but could find a niche as a backup that could start in a pinch.

Erik Cook

• Height: 6'6"
• Weight: 318 lbs.
• Arm Length: 33 7/8 in.
• Hand Size: 9 3/4 in.
• College: New Mexico
• Conference: Mountain West

Cook has been a quality offensive lineman for the Lobos over the past three years and has started at all three positions: tackle, guard and center. He may be a little tall for the center position as he would be facing a lot of nose tackles that would have a natural leverage advantage on him. He is a natural knee bender that does a good job of playing with a good pad level and will leverage his blocks. He can struggle when opponents get to, or past, the edge and he needs to recover and square back up on the block. He lacks the lateral range to play on the edge and is best suited to play guard or center where he has the potential to eventually develop into an adequate starter.

Chris Degeare

• Height: 6'4"
• Weight: 325 lbs.
• Arm Length: 34 in.
• Hand Size: 9 3/4 in.
• College: Wake Forest
• Conference: ACC

DeGeare is a physically gifted lineman who has struggled with the mental aspects of the game as well as college. He missed the 2008 season by being academically ineligible and is not aware of twists, stunts and games up front by the defensive linemen. He can be quick out of his stance but often ends up getting behind on blocks because he is late to react to movement. He appears to wear down during the course of most games and may need to loose some weight in order to improve his conditioning.

Kurtis Gregory

• Height: 6'4"
• Weight: 305 lbs.
• Arm Length: 33 in.
• Hand Size: 10 1/4 in.
• College: Missouri
• Conference: Big 12

Gregory is a high-character lineman who played tackle in college but projects as a better fit inside, at guard, for the next level. He has marginal initial quickness and is not a natural knee-bender so he struggles to leverage his blocks. He understands blocking angles and makes quick decisions but is simply not quick or agile enough to project as a make-it at the next level. He does not do a great job of bringing his feet with him and often ends up falling off blocks and going to the ground. If intangibles were a determining factor, he would be a starter, but he is not athletic enough to be more than a backup, at best.

Joe Hawley

• Height: 6'3"
• Weight: 297 lbs.
• Arm Length: 33 1/8 in.
• Hand Size: 10 5/8 in.
• College: UNLV
• Conference: Mountain West

Mike Iupati

• Height: 6'5"
• Weight: 331 lbs.
• Arm Length: 34 3/4 in.
• Hand Size: 10 5/8 in.
• College: Idaho
• Conference: WAC

Iupati is a massive guard that started three years at Idaho although he did miss some time in 2008 after dealing with offseason shoulder surgery. He is one of the more powerful blockers in the draft and once he gets his hands on opponents it’s pretty much all over. Iupati was born in American Samoa and English is not his native language which can slow down his progress when it comes to learning new schemes and the playbook. While it may take Iupati a bit longer to develop into a front line player, he could have a long and productive career once he settles in.

John Jerry

• Height: 6'5"
• Weight: 328 lbs.
• Arm Length: 34 in.
• Hand Size: 9 3/4 in.
• College: Mississippi
• Conference: SEC

Jerry is a massive lineman that moved to tackle for his senior year at "Ole Miss" but will need to move back inside to guard for the next level. He can engulf and overpower opponents once he gets his hands on them but can also struggle against speed when playing on the edge. He is not a natural knee bender and tends to let his pad level get too high on a lot of blocks. He is more of a mauler and brawler than an explosive blocker and knocks opponents off the ball. He could stand to lose some weight if he wants to become a full-time player at the next level.

Mike Johnson

• Height: 6'5"
• Weight: 312 lbs.
• Arm Length: 32 1/2 in.
• Hand Size: 9 3/4 in.
• College: Alabama
• Conference: SEC

Johnson is an all day sucker that, while he doesn’t dominate or punish opponents, simply knows how to get the job done. He has played and started at both guard positions as well as both tackle positions while at Alabama. He understands angles as well as his limitations and does an excellent job of not letting himself get into situations that expose his weaknesses. He lacks top sand in his lower body and can be driven back into the pocket by powerful interior defensive linemen. He is the kind of player that finds a way to become productive blockers at the next level.

Ted Larsen

• Height: 6'2"
• Weight: 304 lbs.
• Arm Length: 32 in.
• Hand Size: 9 3/4 in.
• College: North Carolina State
• Conference: ACC

Shawn Luavao

• Height: 6'2"
• Weight: 315 lbs.
• Arm Length: 33 in.
• Hand Size: 9 1/2 in.
• College: Arizona State
• Conference: Pac 10

Marshall Newhouse

• Height: 6'4"
• Weight: 319 lbs.
• Arm Length: 34 in.
• Hand Size: 10 1/4 in.
• College: TCU
• Conference: Mountain West

Eric Olsen

• Height: 6'4"
• Weight: 306 lbs.
• Arm Length: 32 1/2 in.
• Hand Size: 9 1/4 in.
• College: Notre Dame
• Conference: IA Independents

Olsen is a good college center with excellent size, strength and technique. He works his blocks hard and will fight from snap to whistle to get the job done. He does a good job of getting a fit with his hands to control and steer opponents but does not always bring his feet with him when reacting to movement. He is not real nimble or quick getting to the second level when on the back side and is not real effective when blocking in space. He is not a natural knee-bender and struggles to keep his pad level down to leverage his blocks. He has a chance on size, competitiveness and intelligence but lacks the physical tools to be a front-line player.

Alex Parsons

• Height: 6'4"
• Weight: 309 lbs.
• Arm Length: 31 3/4 in.
• Hand Size: 10 in.
• College: Southern Cal
• Conference: Pac 10

Parsons is a decent-sized lineman with good initial quickness and agility. There are a lot of things about him that are above-average-to-adequate, but there is nothing that really jumps off the screen at you. He can be overpowered by bigger interior linemen, and he lacks the haunch power to hunker down and stop the bull rush. He is more of a finesse blocker than a heavy hitter who can jar opponents back to their heels, and he will need to fit with a team that does a lot of zone blocking and does not require its linemen to overpower opponents for the run game.

Mitch Petrus

• Height: 6'3"
• Weight: 310 lbs.
• Arm Length: 33 3/4 in.
• Hand Size: 9 1/2 in.
• College: Arkansas
• Conference: SEC

Petrus is a two-year starter at guard after spending time at tight end as well as fullback. He missed the 2008 season due to academic suspension due to a change in majors and falling short of academic eligibility requirements. He is still learning the position but shows enough raw talent and athleticism to make you think he has a chance to be a quality starter with work and practice. He shows excellent body control and balance in his blocks and is a natural knee bender that can leverage his blocks against bigger opponents. His hand use improved during his senior season and could become a strength as he gets more comfortable with techniques.

Maurkice Pouncey

• Height: 6'4"
• Weight: 304 lbs.
• Arm Length: 32 1/2 in.
• Hand Size: 10 in.
• College: Florida
• Conference: SEC

Pouncey is a versatile lineman that has lined up at both center and guard. He is a squatty, quick-footed athlete that can roll his hips to redirect and adjust to movement or sink his hips to hunker down against a powerful bull rush by big nose tackles. He is quick with his first step after the snap and quick to get a fit with his hands but will let his weight get too far forward at times. Pouncey had surgery to repair a torn labrum in his shoulder in May of 2009 and durability could become a concern down the road. He should be quick to see the playing field thanks to his versatility.

Dace Richardson

• Height: 6'5"
• Weight: 320 lbs.
• Arm Length: 33 1/2 in.
• Hand Size: 9 3/4 in.
• College: Iowa
• Conference: Big 10

Richardson is another in the line of Iowa linemen that fits the profile of what NFL teams are looking for and has all the physical and mental tools to play at the next level. The only problem is that he has missed nearly two full seasons due to medical issues and may be considered too much of a medical risk for teams to take a chance on him. He understands angles and knows how to leverage his blocks and keep his feet under him and alive. He has excellent lateral range in pass protection and does a good job of recovering and righting himself to react to counter moves. He has played both left tackle as well as guard, as a starter, for the Hawkeyes.

Chris Scott

• Height: 6'4"
• Weight: 319 lbs.
• Arm Length: 34 1/8 in.
• Hand Size: 10 3/8 in.
• College: Tennessee
• Conference: SEC

Mike Tepper

• Height: 6'5"
• Weight: 324 lbs.
• Arm Length: 32 1/2 in.
• Hand Size: 10 1/4 in.
• College: California
• Conference: Pac 10

Tepper started at left tackle for the Bears during his senior year after missing his fifth year and being granted a sixth year by the NCAA. Previously he had started on the right side and that is probably a better fit at the next level. Tepper also missed the 2005 season after major surgery to repair a broken leg suffered in a car accident. He is an adequate athlete with above average body control and a good feel for angles and how to position himself. He can struggle when out in space and may eventually slide inside to guard to compensate for his lack of lateral range. He is a bit top heavy and will overextend into blocks too often causing him to lose balance or fall off blocks.

J.D. Walton

• Height: 6'3"
• Weight: 300 lbs.
• Arm Length: 33 3/8 in.
• Hand Size: 9 1/4 in.
• College: Baylor
• Conference: Big 12

Matt Tennant

• Height: 6'5"
• Weight: 300 lbs.
• Arm Length: 32 1/4 in.
• Hand Size: 9 1/2 in.
• College: Boston College
• Conference: ACC

Tennant is a three-year starter for the Eagles that has become an excellent technician that knows angles and how to use his hands to control and steer opponents. He is quick into blocks after the exchange and does a good job of moving his feet and adjusting to movement but lacks the raw power and lower body strength to dominate like the elite centers. He does a good job of finishing his blocks off when he can and goes from snap to whistle. He still needs to fill out his frame but will probably never be an overpowering blocker at the next level.
