He wants to play. He just does not want to play here and he simply does not want to come right out and demand a trade, because he does not want to seem like a jerk to the fans and team who have supported him.
It seems to me that he is trying to do the right thing. He wants to play closer to his home but he does not want to demand a trade publicly. The Bills should (and may already have been) be looking to see if Houston, Dallas or TN has interest in trading for him. It is unlikely, but it is worth a chance. Otherwise, just release him and let him get on with his life. He really isn't in the longterm plans for the team anyway. Just move on.
