I can't think of a team that would allow a good LT or center just walk. Like Denver let Paradis go because he's fuging terrible, and the Vikings let Kalil go for the same reason, but what team would be dumb enough not to pay a good LT or center?
I absolutely love T. Moss, all these guys would be a good addition. Especially if Olsen is gone. Although don't sleep on the current TE's we have. Thomas and Manhertz are serviceable. I think adding a pass catching TE that can stretch the field would be a great addition.
