The Jury is out as to whether Tebow has truly made it though I do not begrudge his success one bit.
Tebow is nearly as fast as Denard, and 50 pounds bigger and quite a bit stronger. He also has a better arm, which is disguised by a shitty delivery. When he has time, as against Pittsburgh he throws quite well. When he doesn't have time, well last night was a good indication. Robinson can barely stand up to an entire Big 10 season. Tebow did quite well in a much more physical and athletic conference where a better brand of football is played. Robinson could not stand up to an NFL season.
His staying in school makes sense, he's not going to get drafted as a QB, he's not that good. He could end up like Randal El. Decent NFL carer that in 5 years no one will remember.
