How can you judge a college QB on his winning or not winning the big game in his career? That's sort of like saying that Marino isn't one of the best QBs ever because he didn't win the superbowl. Football remains a team game on every level, so it doesn't really matter whether or not "1" player happens to be on a team that wins something significant. What we should be judging Quinn on is his individual production which has been great. He has progressed nicely every year and threw for 37 TDs and only 7 INTs, with a 61.9 comp pct rate and a 146.65 QB rating his senior year.
Your argument that he didn't get hype until Weiss came around is lacking. The 2 years of his career before Weiss came are commonly referred to as "freshman" and "sophmore" year. To expect "greatness" in those first, learning years is ludicrous. What you want to see out of these years is progress; which is what Quinn has displayed. Let's also not forget that most college football players hardly ever see the field in their first 2 seasons; let alone at the QB position and a very high profile college. Weiss also runs a pro style offense, which should be an indicator the Quinn can handle a similar system in the NFL.
We would be extremely fortunate to land Quinn at #9. Look at the numbers, they speak for themselves. Don't judge the man's college career on the Sugar Bowl. Judge it as a collective whole.
