I don't know Oviedo. When Stapleton went down, we did not have an experienced RG. Essex was hardly "entrenched" in the position. Maybe the reason was more that Urbik wasn't ready last year (at least I hope so). Maybe the team didn't give him a fair shake.
If the Steelers are talking to Iupati, I'd have to think that they are not super high on Urbik. I hope Urbik pans out after they spent a third rounder on him. But, if they are going for more athletic linemen, Urbik may not be the guy.
