Flozell Adams: Not only the anchor of the O-Line, but the eldest statesman of the team now, along with Ellis.
Marco Rivera: Played through the back injury last year, but is looking to get his power back this season.
Kyle Kosier: He won't be Larry Allen, but that might not be a bad thing. His versatility to play other positions could be valuable.
Al Johnson: Has the edge to beat out Gurode again at center, but there could be more rotating at the position.
Andre Gurode: Re-signed to a one-year deal. Has some value with his ability to play the three inside positions.
Jason Fabini: The Jets thought he had little left in his tank. Let's see how he responds when the pads come on.
Rob Petitti: Despite his rookie struggles last year, has 16 starts under his belt. Throw in more strength and confidence and the Cowboys might have something here.
Marc Colombo: Could be an ideal fit to back up left and right tackle positions.
Stephen Peterman: Entering his third season, time is running out. Parcells wants to see more versatility from him.
Cory Proctor: Joined the team last season from Detroit's practice squad. Might have to beat out Peterman for the final backup spot.
Pat McQuistan: Showed a few things in the mini-camp. Of course, without pads, it's a different story.
Shannon Snell: Practice squad player from a year ago. Might have hard time doing any better than that this year.
Dennis Roland: Will stand out because he is the tallest player on the team at 6-9. Now we'll find out if he's got some game to go along with the height.
Matt Tarullo: Parcells liked him enough last year to keep him on the practice squad. He's got value by playing guard and center.
E.J. Whitley: Bad news for the Texas Tech rookie is that his ACL injury will keep him out all season. The good news is that he'll be around all season.
Without Allen, Cowboys Need More From O-Line
