I do not remember Jerry practice at RT last year at all. From first day of camp he was firmly planted at the RG position. I missed about 3 practices but do not remember reading anything about him at RT. I do not see him as a starter anywhere. He is talented but there is a factor no one can determine that is needed to make your mark in the NFL. Thats determination and it appears he simply does not have that. He is the type of guy that does what he needs to get by and it ends there.
As far as the lineup and again with the Grace of God barring injuries it looks like Long, Incognito, Pouncey , Carey, either Columbo or Murtha, IMO Garner and then its a big tossup between Jerry, Feinga or Berger to dress on game day. IMO, game day dressed Olineman should be the first five plus Murtha Garner and one of the other three. It seems like they probably will keep Berger as a legit center backup OR, if they sign OHara, which I doubt, then things would change, I would have to rethink that and it possibly would be Murtha, Ohara and Garner most likely actice on game day. They put 8 Olineman active on game days and the rest are either inactive or on the PS.
