I'm disappointed by all the attacks on Chiles and everyone giving up on him. He is only 4 games into his second year, without the luxury of having redshirted, and has played QB on an extremely limited basis (not to mention that he has been cross-training at WR since the spring/fall practices, further taking time away from his QB training).
Coming into the year, everyone was ready to give up on him because he couldn't throw the ball. Now, he has missed only 1 pass (although a couple of others weren't great), and everyone is giving up on him because of his decision making.
Sure he has made some stupid (and costly) mistakes. But give him some time to develop. Its not like Vince had great decision making his first year. Chiles is clearly pressing, trying to make more than is there in his limited opportunities. Put him back as the back-up QB, let him train exclusively at QB, and learn the position. Get him as much experience as possible in meaningful situations (or at least let him run the whole offense when he is in there).
And while his running numbers may not be great, I think that has as much to do with the predictable play calling while he is in there and other teams stacking the line (because they still aren't concerned he is going to beat them with the pass like they are with Colt). We have all seen glimpses of his athletic ability running the ball, and while it is possible that he has put on too much weight or something, I doubt he has just completely lost that.
Maybe he won't ever become an elite QB, but I think he has shown enough signs to believe that the game will eventuallyl slow down for him and he will get it. And when that happens, he will be dangerous.
But yeah, I have no problem shelving the Q package, or at least limiting it to a couple of trick plays.
