I think Kofi was a project all the way. I am very interested to see what he looks like this year in preseason games. The athletic numbers are all there, but the game wasn't.
I think we have the bodies and the coaches have the track record for finding guards, I am not too worried about that position. And we have Murphy, Spriggs, McCray that have played tackle when needed. I only worry about the back-up C spot because I know zero about it. Tretter and Linsley were picked in the 4th and 5th rounds respectively. With so many picks, I don't see why that investment can't be made again. Of course, I could be worrying about nothing and we have a future starter on the roster already, it is a complete unknown.
