If Wells isn't signed to a new deal, the offensive line is ultimately screwed. I don't care if they go and get Konz from the draft because you can just never put that much stock into a rookie (at such an important position).
I may be the only one, but I just do not like the way Sherrod played when ever he did get the chances. Maybe it was the stunted development from moving to left guard for a competition? With that said, the kid has played left tackle his entire life so how much more is there to learn about the left tackle position? Maybe I am a little off base since it is the NFL but when I was at the Kansas City game (fml), I was scared for Rodgers when Sherrod entered the game.
Hopefully he can develop, but I don't see him being a premier LT.
