He did look quicker in 12 and Johnson said something about that on his radioshow. It had to do with a play in the BYU game. Johnson told Vad that in 12 he would have had the legs to get that first down because he wasn't the starter then. Playing every series just makes you a step slower. I think he played his heart out in 12 for playing time. He knew he had the job in 13 so he didnt do that so much. Once he realized this wasn't for him, he sure wasn't going to hurt himself.
