Some days John St. Clair overachieved on other days he way underachieved or played how we thought he would depending on your viewpoint, but many think St. Clair has shown enough to warrant a new contract.
The question is where to put him. He had too many games where Kyle Orton was getting blasted all day, but he may have some value at left guard or as this article puts it:
We knew this would be coming eventually. Tait's skills have gone down little by little each year, maybe rotating St. Clari in can prolong his shelf life and give him a few more servicable years.
So far as an offensive linemen in the draft NFLN's Mike Mayock says this isn't the best year to pick up a guard.
He is impressed with two of the bigger guys Herman Johnson out of LSU (6-7, 386) and Kraig Urbik (6-6, 332).
