The weakness has as big of an effect as a strength. A guy like Whitworth elevates the play of anyone next to him. Edwards was looking very good most of the season. Sandwiched between Noteboom and Blythe, he is not looking that good. If they would have upgraded just Blythe alone it likely would have made an enormous difference. A stud center would improve play of both guards, which in turn makes things easier for both tackles. I know many here think the answer for the offensive line is on the roster, but I don't see a star caliber center on the roster. If none of them could unseat Blythe, who is bad, then how good can they be? One guy they liked as a guard or Center, but past up in round two by trading back is Elgton Jenkins, who just made the Pro Bowl. I get excited when I read about Olineman they really like, but its alk for naught. I see three OL positions that could stand to be upgraded and one really important future one. You're correct. Snead and McVay dug themselves a hole.
