The NFL draft is a crap shoot. Sure things turn into busts and low round picks everyone overlook turn into All-Stars. More often than not high picks are better than low, but there's no exact science. Quarterbacks are even more risky, they boom and bust all over the place.
That's enough padding, the question is at what point would Tim Tebow be worth the risk for the Steelers?
If you say never because the Steelers have Ben and Dixon, just remember we aren't talking about starting Tebow, at what point is an athletic hard-working QB with huge mechanical flaws worth the risk? 3rd round? 5th? *awkward jump*
The reason I'm asking is the Steelers are pretty well set on offense at skill positions, they have good depth and it will be hard for late round rookies to make the squad. Tebow could easily be on our active roster as a 3rd QB behind Dixon and have plenty of time to fix his motion with no pressure on him. Two years from now he develops and gets in and shows he can play we can turn him into a good draft pick because people will still remember him.
I know he irritates people with how much crap gets said about his faith, but put him on our team and he'd learn to tow the line pretty quick, and he wouldn't be the focus of attention on the Steelers.
Personally If he's around in the 4th I'd say go for it (he probably won't be) but before that he just isn't worth passing on other players. If he goes in the first round I'll feel sorry for him. He can't succeed with that kind of instant expectation on him.
