Trading Gates away is like trading away a stud WR. The reason why you missed out on a stud WR in the draft, is probably because you drafted Gates early. I really think you should be able to get a good WR straight up for Gates. He's an upgrade FOR EVERYEONE, the only exception being the guy with Witten who wouldn't need Gates. Not saying you'll get a R.Moss, Ocho Cinco, but maybe a Plax or Wayne if the other guy really needed a TE and had the depth.
