Look at his qbr and completion percentages. He was a different type of runner than hill. So its hard to say which is "better." He was bigger and stronger than taysom (1" and 15 pounds) and had more of a power running side to him than taysom. Taysom is faster and quicker but not the short yardage back tebow was (although taysom is pretty good).
Tebow was also putting unheard of scoring on good sec defenses. He made some jaw dropping throws that I just haven't seen from Taysom, yet (see FSU 2007). I'm not trying to bash Taysom in any way, but he isn't as good as tebow was. Taysom is a phenomenal player but he has a ways to go to catch up to one of the best college qbs of all time.
