I say no to the trade because he is still worth more to the Bills than any other team. The biggest problem with him is the expectations, he is not the type of WR who is a #1. I thought at best he was a #2, he was not known for his route running, speed or being shifty, he is big and physical. He projects well to win jump balls and block downfield.
The bigger issue is the the Bills have a weak pass game plan. Three guys got here to produce less than they did with lesser QBs. So, I do believe he is more talented than his production suggests.
Bean did not miss on the talent but did miss on the guy. I would not try to trade him since he has no value. They should try to develop him as he does have tools that could be useful. If at the end of the next preseason the light doesn't go on for him trade him for a bag of used footballs or cut him and move on.
