Why? Because he stares down his target, doesn't go through a progression, has little to no anticipation with his throws, and spotty accuracy at best. Thats a few off the top of my head. Admittedly I haven't seen him this year, so I'm basing this off the last couple of years. If you say he's improved in all these areas this year I'll take your word for it, but if he hasn't...well, even a bad defense has got to be licking its chops right now.
