It's an interesting comparison, though not a straight one. Their freshmen numbers:
Tim Tebow
Passing: 14 games, 22/33, 66.7%, 358 yards, 10.8 ypc, 1 int, 5 TD, 201.73 rating, 2.4 att/g, 25.6 ypg
Rushing: 14 games, 89 attempts, 469 yards, 5.27 ypc, 8 TD, 6.36 att/g, 33.50 ypg
Terrelle Pryor
Passing: 13 games, 100/166, 60.2%, 1311 yards, 7.9 ypc, 4 int, 12 TD, 145.62 rating, 12.8 att/g, 100.8 ypg
Rushing: 13 games, 139 attempts, 631 yards, 4.54 ypc, 6 TD, 10.69 att/g, 48.54 ypg
Tebow clearly has better numbers, but it's not a great comparison: he wasn't the starter and was primarily used situationally. I was inclined to think that Tebow's numbers were inflated by Florida's offense, but Florida averaged 29.7 ppg in 2006 whereas OSU averaged 27.6 ppg in 2008 - not a huge disparity. Terrelle has a world of talent, but I don't think it's fair to compare him to Tebow (yet).
