Here's a couple of other internal options:
Ramon Foster, T
Foster is a natural tackle. I'd like to see him get the first shot at the job. He's a nasty lineman and played well in limited duty last season and during this year's preseason. He's comparable in size to Flozell Adams and he's got some speed and quickness that's valuable for the position. He may not be a long-term fix, but he could provide a steady hand in the remaining eight games.
Chris Scott, T
Scott is another natural tackle. He was just activated today to replace Starks on the roster, but he's coming off an injury of his own and has no time in this offense. He's a rookie and his injury occurred prior to camp. With that much inexperience, its hard to imagine him getting into a game for a few weeks, although he could play his way into the lineup by doing well if and when called upon.
Tony Hills, T
Hills is the other tackle on the roster. He's never lived up to his draft status (fourth round, 2008) and he's slightly undersized. He has the speed, but he's never been able to stop rushers from beating him. He could be a serviceable backup, but he's never seen much time in the NFL because he's simply not that good. They may need him now.
Trai Essex, G
Essex has been playing guard for most of the last two years. He's had experience at left tackle before, however. He was a decent relief option there in his first seasons before he became a starting guard and he knows the ins and outs of the position. With Doug Legursky emerging as an excellent player at guard, Essex may be expendable there and could be moved back to tackle.
