1. San Diego Chargers
Who: QB Philip Rivers; RBs LaDanian Tomlinson, Darren Sproles

Add/subtract: When you have the NFL's top-rated passer and two backs combining for 1,440 rush yards, 81 receptions and 18 TDs, you don't need to add much. The Chargers went big on power, drafting two offensive linemen and two defensive linemen with their first four picks. Of course, getting Shawne Merriman back may be the biggest "add" of all.

Questionable: How much longer can L.T. continue being L.T.? And will Rivers' maturity finally match his talent? Maybe more to the point, if Merriman and that defense start setting up this backfield on short fields, how good can this team be?

The thought: Rivers and the Bolts got a delicious taste of what it feels like when it all comes together. And L.T., one of the great tailbacks in NFL history, has at least one year left, and his understudy would start for more than a few clubs.

2. New York Giants
Who: QB Eli Manning; RBs Brandon Jacobs, Ahmad Bradshaw

Add/subtract: The Giants will miss 1,000-yard back Derrick Ward and WR Plaxico Burress (who they sorely missed last season). But the Giants drafted two WR's (Hakeem Nicks, Ramses Barden), one TE (Travis Beckum) and an OT (Will Beatty) in the first three rounds to add playmates for an already elite backfield.

Questionable: The Burress aftershocks should be over, but are they?

The thought: This top-10 offense was on a mission to improve its skill positions. It will be difficult to keep it from topping the 427 points it notched last season.

3. Dallas Cowboys
Who: QB Tony Romo; RBs Marion Barber, Felix Jones, Tashard Choice

Add/subtract: Terrell Owens. You decide if that's an addition or not.

Questionable: Can Roy Williams become the deep threat Romo needs to force defenses out of eight-man fronts?

The thought: Romo's passer rating (91.4) was significantly higher than his U.S. Open qualifying score (80), and that's a good thing. Instead of handing clubs to caddies, he'll be handing pigskins to the three-headed monster at tailback. Having all those options will allow Romo to play relaxed and balanced -- and talk to Jason Witten without T.O. getting suspicious
