Playing QB in this league is tough. I can't hate on a man's work ethic without knowing exactly what it is. From everything I've read about him, I seriously doubt his work ethic has dropped. He had 2 concussions in 2 years, has his OL downgraded, got a different OC, and lost his best weapons due to injury in these short 2 years after his rookie year. Throw that in with teams having more film on him and the drop-off makes sense. Maybe he needs to change what he does in the offseason to adapt better, but I doubt he has an issues with work ethic.
