Bryan Broaddus concludes his offensive positional breakdowns by reviewing guards and centers. Broaddus has been critical of Leonard Davis' and Andre Gurode's play in 2009 and expounds on those criticisms here.
I see guys running through and making plays on [Gurode]. I see guys getting off blocks and making plays. He shouldn’t have been a Pro Bowler last season.
In the San Diego game, when the Cowboys couldn’t punch the ball in from the 1-yard line, Davis was a significant part of the problem because he did a poor job of adjusting to the run-through linebacker.
Broaddus also mentions that he anticipates Travis Bright being the guy to finally knock Pat McQuistan off of the roster. DC.com also recently discussed Bright's versatility and the value that it offers the roster.
According to Broaddus' projections, we can expect to see the following as backups:
Alex Barron - T
Robert Brewster - T
Montrae Holland - G/C
Travis Bright - G/C
...with Sam Young and Pat McQuistan possibly vying for a tenth spot. It's difficult to carry starter caliber offensive linemen on your bench in today's NFL, but I have to say, those four don't inspire a lot of confidence for me.
