I don't get why people on here are so down on Rattler. He was a rookie playing behind possibly the worst OL in the league and had lost ALL of his WRs replaced by JAGs. His play still flashed some high points/talent regardless of his team weaknesses. No decent running game to take pressure off of his throws. No play action to keep the D off balance. Too many adversities to try to overcome as a Rookie.
I think who Rattler can be is still to be seen. It wouldn't surprise me if our new QB Whisperer/Coach can mold him into a more than decent starting QB.
He may also fail to make the transition to Pro QB. My point is that I don't think anyone here can tell that yet.
