The answer is that MB3 is working out in Miami. Nick Eatman has a very good article looking at the situation involving Marion Barber and to a lesser extent Ken Hamlin. Both players have yet to sign the tenders and the thought is that their agents and the Cowboys are trying to hammer out long-term deals. Eatman wonders why they can’t be at Valley Ranch anyway seeing as how both will be playing for the Cowboys this year. They have until June 1^st to sign their current tenders and after that point the Cowboys can actually lower them. I wouldn’t expect any shenanigans like that occurring but the underlying point of them not being at the Ranch is valid. Surely Felix Jones and Tashard Choice could benefit from MB3’s presence even though he’s one of the quietest Cowboys on the team. They could watch his work ethic and follow his examples in their first steps towards having an NFL career. On the other hand, Hamlin is considered one of the vocal leaders on the defense and could definitely be helping guys like Jenkins and Scandrick get acquainted with the Cowboys secondary. It’s not that unusual for players who have yet to be signed to work out elsewhere during the offseason, sometimes even players who are signed don’t make regular trips to the facilities during this period. But it sure would be nice if MB3 and Hamlin were there. Chris Canty, another player who still hasn’t signed his tender, has been present at all Valley Ranch functions.

MB3’s situation is getting tricky considering the initial reports about the money he’s asking for – LT-type money. The Cowboys are not going to go down that road and may be taking a page out the Romo playbook by waiting to see how MB3 performs this year as the undisputed starter. If the Barbarian proves to be a feature back that can be counted on to carry the load, they might be willing to give him a fairly sizable contract thought I doubt they are going to break the bank the way Drew Rosenhaus would like them to do. But at least the Cowboys have some insurance by drafting El Gato and Taster’s Choice, but those two have to prove it on the field before they can turn into real leverage in the MB3 negotiations.

The Cowboys also are bring in Ray-Ray’s little bro, Keon Lattimore. Being an ACC guy I watched Lattimore play on a few different occasions and thought he was an OK back. When he told his older brother Ray Lewis that he had signed an UDFA contract with the Cowboys, Ray broke down and cried. 

"When he called me and said, 'Bro, I'm a Cowboy,' the tears came easy," Lewis said. "I love him like a brother, but I've always looked at him like my child, too. When your child accomplishes something like that and you know you had a major part in it, it's an amazing feeling.

"The emotions I felt that day were overwhelming."

Zach Thomas fells like he’s ready to go and that the injuries are not going to bother him this season.

"When I see my game decline or I'm at risk health-wise, I'll shut it down. There are guys that can't turn the page. I'm not one of those guys. I know I still have game."

I’ve tried to stay away from Romo’s romantic life but I had to pass along this zinger in the San Jose Mercury News. 

Jessica and Tony: Well, are they or aren't they?

It's The Great Debate: Are Tony Romo and Jessica Simpson done? "Extra" and "Access Hollywood" say no. TMZ.com and the Dallas Morning News say yes. And the Cowboys are just thankful to have the calm, stabilizing influence of Terrell Owens and maybe Pacman Jones.

Nice. BTW, if you’re interested, here’s a pic of the supposed new-woman Romo’s pursuing. Gee, you think Romo might have "a type?"

Patrick Crayton on Tony Romo's singing:

"That's the first time you got to hear Romo sing," Crayton said. “We get to hear it daily, and it's like horrible. It is bad. He finally got a replay back of it, and he finally admitted it. I'm like, 'Dude, I've been hearing it for four years. You're just now admitting that?'"

Zach Thomas on leadership:

"Leadership is shown by actions," Thomas said. "If you're making plays and doing everything the right way - doing what they're telling you to do in the weight room, showing up for everything, being consistent and being accountable - that's leadership. It's not giving a great pep talk. If you give a great pep talk and do all the right things and don't play well, there really isn't much leadership there. My leadership is coming in and playing well and getting the respect of my teammates."

Brian Stewart on the meeting with Roy Williams:

"I think all three of us left that meeting feeling comfortable that we've got an open line of communication," Stewart said. "Everyone knows where everyone stands. The past was the past, and now we've got a chance to move forward."

Jerry Jones on Marion Barber and Ken Hamlin:

"We've had visits and talked with them and their representatives," Jones said. "If their contracts were done, then I would expect them to be part of OTAs and minicamps. ... We expect to [make deals], and I think we'll do that certainly within the time frame that's good for everybody."

 Julius Jones' new position coach on his time in Dallas:

“I think playing for Bill Parcells in Dallas really helped bring out the best in Julius and he’ll tell you that,” Ruskell said. “That’s what he talked about with us when we brought him in as a free agent.

“Julius ran really hard and took advantage of what that line was trying to do in Dallas. With what we’re trying to do in changing our running game, I think that fits.”

Ken Hamlin's interview on Sirius radio.

Hat tip to DCFanatic for the Hamlin interview.

The Cowboys have set the dates for training camp in Oxnard.

Those camping dates are official: The Cowboys will report to training camp July 24 in Oxnard, Calif., and begin their three-week practice schedule on July 25.

[snip]

The Cowboys are tentatively scheduled to leave Tuesday, Aug. 12 for Denver, where they'll practice with the Broncos on Wednesday and Thursday of that week and then on Friday by themselves before Saturday's preseason game on Aug. 16.

The team will return home after the game to finish their preseason schedule against Houston and Minnesota at Texas Stadium.

Uh oh, Marion Barber and Ken Hamlin haven’t been showing up for workouts at the Ranch. Both guys have yet to sign their tenders. 

The Cowboys are almost seven full weeks into their off-season conditioning program, which is nearing its halfway point.

While nearly all the players have participated in full, Marion Barber and Ken Hamlin have not been among them.

When the Cowboys conduct a three-day OTA (organized team activity) practice schedule next week, it's likely those two players will not be in attendance.

Jerry’s not worried, yet.

"Not at all," Jones said during the team's annual golf tournament for sponsors, held at the Cowboys Golf Course in Grapevine. "I would like them to be here. But right now, we're working on a few things. I think when the time comes, they'll be ready to go."

More on Barber in this Star-T article and a little about Pacman Jones. 

Jerry Jones said suspended defensive back Pacman Jones has been in Dallas since the team traded for him, but that he remains unable to participate in any function at the team facility. Pacman Jones and Jerry Jones have visited, but the defensive back has not taken a physical from the team.

The NFL will have to approve whenever Pacman Jones is allowed to work out with the team at the facility.

"I do want him to come in and be a part of the team activities and off-season conditioning," Jerry Jones said. "I understand why he can’t. … He does know what he needs to be doing to prepare himself strength wise."

Jerry Jones gives a vote of confidence to Roy Williams, here.
