I agree that he's a better game mgr, however, I also think its made him a worse overall QB. Now he seems scared to take off when a good running lane exists because the coaches want him to be more of a pocket passer (so he doesnt get hurt). He's not a great passer, nor do I believe he ever will be. They've taken a great, ridiculously fast runner who was a poor thrower, and turned him into an average thrower and an average runner.
IMO it looks like opposing defenses don't account for him as a runner like they used to and have no problem rushing straight at him instead of worrying that he might get out of the pocket.
Since he's no longer as effective as a runner, the whole running game is less effective too, and IMO its resulted in less wide open receivers (where passes dont have to be as accurate) compared to last year and earlier in the season, thus, forcing him to be more of a pin-point passer for which he's not equiped.
I still have visions of Washington, K-State, and Okie State from last year. Unfortunately, I dont think that QB exists anymore. Not so much because he couldn't be, the coaches have just tried to coach it out him.
