I don't think you trade him, unless you think you can get something monstrous in return.
Tough schedules for football teams are often GREAT schedules for FF QBs. If you're not invested in the NFL team, and have the QB, you WANT the team to be struggling... dog fights. You WANT them playing from behind. You want them to HAVE to throw. Tough NFL schedules hurt RBs, but in some cases, they MAKE FF stud QBs.
Look at last year, McCown and Warner throwing 300 yard games etc, because they were always behind. Here we've got one of the best QBs in the game, and he's going to be forced to throw more frequently. That's a GOOD thing, IMO. Maybe it'll help Chad Johnson stop sucking too.
