For all the attention EJ/Orton has gotten, the guard play is a bigger issue. Pears, Williams, Urbik, and Richardson have been a disaster so far. Richardson may get better.
I would IR Williams now and sign another guard or back-up center. I would then start Urbik at RG, give Hairston a shot at RG, or the new signee. I would delay this action until the bye week but Pears needs to be demoted to back-up tackle/guard during the bye.
