Prince and Hill were terrible

[*ochocincos*]

Prince and Hill clearly aren't ready to be starters, but it's unrealistic to think they are going to be anywhere close to good filling in.
Hill is a Day 3 rookie and Prince hasn't played much either after being out all year.
Prince has been solid as an extra OL though this season on limited snaps.

But this is what happens when your starters go out. Lesser talented players have to fill in. And going from a 4-11-1 team last year, the team likely can't afford to fill real quality depth because they need to try to get as many good starters with the resources they have first.

With that said, I'm 100% in favor of getting a new C next year. Gimme Linderbaum in the draft (although Bengals will probably draft too late for him) or go get Jason Kelce or Ben Jones in FA.
