KJ size and morphology makes for harder, slower recovery from knee injury which is derived from multiple ACL studies. I know he is not ACL, but the similarities to recovery are influenced by his weight an build. It takes some digging and is sport specific but there are retrospective and occasional prospective studies that show a differenc in healing by body morphology. KJ will be a slow healer is my prediction. He definitely looks overweight in his face way more than when he arrived. KJ is trending towards looking like Jamarcus Russell and not Sham Newton, I hope he emulates either in college success but he does not seem to be the ideal Briles QB.
