You just argued my point, he didn't do well against either of them and they are not even comparable to what he would see in the NFL.
I didn't argue for you, yours is completely invalid. I am not about to look it up, but I'm sure there are plenty of examples throughout the years of college QB's who struggled against good defenses who went on to be anything from a serviceable starter to a pro bowl QB.
Ask any draft scout, and I'm certain they'll tell you QB is among the most difficult positions to scout since there are such a huge variety of factors that contribute to a QB's success or failure.
When Vince Young was coming out of college in 2005, I was absolutely certain that he would be a failure due to the same knocks you and droski have on Tebow; not intelligent and poor mechanics. You think Tebow's mechanics are bad? Vince Young looked like a freakin' stunt double for Uncle Rico his entire college career, and it was no secret that Mack Brown had to dumb down his offense so Vince could run it. Need I bring up the Wonderlic Test?
Yet look at him now; I was completely wrong about him. And you can tell me this: No explanations, no nothing: Has Vince Young displayed at any point good play at the quarterback position in the NFL? Yes or no.
Like many of you, I don't like Tebow. He jaws too much, mugs for the camera, etc. I hate his sideline preaching. I get dumb chills every time I see it. I am simply saying this: If Tim Tebow gets a fair shot at playing QB in the league, any of you writing him off here and now (which I'm sure is many on this site) have a good chance at eating a lot of crow.
There have been numerous QB's with poor mechanics, that are dumb, that struggled at times in college, etc. that have gone on to be fine at the pro level. You can't tell.
