I don't know about having Newhouse in at LT? i just don't agree with him staying there. Also the ideal of moving Bulaga to LG is more logical imo as he did struggle at RT throughout the year. As far as Sherrod that's the biggest question mark to me. Nobody knows ho good he can be if he got a shot a LT. As a former 1st round pick he deserves a shot at LT.
I know you're not a fan of Newhouse, but he's done okay this year. Could we upgrade him? Sure, but until we're stacked from top to bottom, upgrading an "okay" instead of a "weakness" (center. sorry Saturday, you got old) is a poor value proposition.
As far as Bulaga struggling, I withhold judgement until next year. Rookie year, he looked like a rookie. 2011, he was borderline All-Pro. PFF had him rated the 8th best tackle period, 4th best right tackle. 2012, he regressed. If he was hurt, he'll get healthy and in theory return to 2011 form. Put another way, which is the anomaly: 2011 or 2012? I think 2012, but we'll see.
Finally Sherrod. He doesn't deserve squat. No one does. If he's up to the task, he'll force the staff to start him with his play in training camp. Unless something weird happens (injury to Newhouse, Cleveland clones Joe Thomas and gives him to us) I expect Newhouse to begin camp as the starter again.
