Dangle Kincaid as trade bait. He has been disappointing, but could flourish in the right system. I remember Dallas was after him in the draft.
EDIT: I mean, you have to give something of value to get something of value. Other GMs are not suckers. Some of the trade proposals here assume just that. If you are serious about getting a player who can contribute immediately, you have to give up a good player or a 1st or 2nd round draft pick. We have 3 good TE, we could survive with two.
Me? I suggest the Bills stand pat. The market is crap, as suggested by OP.
