Maybe.
If he has a breakout year and goes to the Pro Bowl, and we finish 7-9, because the defense sucks for some reason... what do you do?
That's basically why I fall back on, if he shows improvement in his game, and is trending up, then we continue. If he's plateued, then you clearly move on. I'd love to see him get a full 16 game season with a decent offensive system.
Edit: Sorry, keep adding comments
