Let's not have a repeat of the Caldwell thread, that went nowhere for 40 pages. That being said I think the only lock going into the season is Welker, everyone else is in a position to be cut or traded if Belichick doesn't like how they look in camp. I think your ideal situation is Moss and Stallworth outside with Welker in the slot, Caldwell being your fourth receiver for when they spread things out.
I think Washington makes the roster over Gaffney if he does well on special teams and shows that he can do well in the system. However if Moss works out and Washington shows signs of struggling then Washington probably wont make the team.
I've been holding out hope for CJ but Reiss keeps mentioning that coaches aren't sure if he is willing to make the commitment to being a good player. I think he is on the PUP list to start even though he will probably be recovered by the end of camp. He will probably be on the IR too barring any injuries.
They will make a spot for Troy somewhere if he is able to play, and I really hope he can recover and come back for one last season. This season is probably the swan song for the older guys on the team and it would be great if they could all go out together on top.
