From a health standpoint he shouldn't be out there? Based on what? If he is in that condition then I don't think he would be out there.
I have been hard on Guyton because he drops the routine throw and his body language after these drops. It is nothing more than not focusing. He had a great game against SMU to start the year and then got a case of the drops. I just want him to live up to his rating coming out of high school. I don't think this has anything to do with his concussion from a year ago.
Give him a work ethic like Johnny Quinn and see what happens.
