I don't think anyone is down on him for his production, its more about the fumbles during critical games in the red zone. Just like a QB, it doesn't matter how productive you are if you consistently turn the ball over. TJ averages a fumble every other game this year, that's way to many. Every QB/RB will have the occasional fumble or interception, but it almost seems like an epidemic with him at this point. No doubt he's been very productive but his ball security has to improve. And considering he has a reputation for it now, teams will be keying on stripping the ball from him which makes it all the more important he improves his ball security.
