Taylor is handling this professionally as far as I can see. He wouldn't be the player he is/was if he didn't want to be out there when healthy, so I think expressing some dissatisfaction is appropriate. There's a long way between that and what AT did last season, IMO.
I have a feeling that, if they wrap the Division, Bye and Homefield up against Buffalo on Sunday, we'll see a lot of Fred in the Miami game, both as a chance to rest BJGE and the Mighty-Mite and as a chance to see what the Pro-Bowler still has in the tank.
