Pretty much an entire starting lineup of NFL players.

OG David DeCastro (Steelers)
DE Thomas Keiser (Chargers)
DT Sione Fua (Panthers)

Luck played on some ridiculously stacked teams. The 2010 team that destroyed Virginia Tech in the Orange Bowl was probably the best team in the country.
Moot point really. There are always going to be 1-2 teams out there that have a flukish amount of NFL talent on the roster. Miami was like that a decade ago. You could say that Alabama is like this right now. Doesn't change the fact that even major college football is a very low level compared to the NFL. Take any team from any conference and you will find very few guys capable of holding down a spot on Sundays. Hence why you have to look at a player's collegiate accomplishments with skepticism. Those defenders that Tebow, Crouch, and Luck torched weren't going to make the grade for the NFL.
The fact that Zac Stacy tore up some scrubs from Auburn, LSU, and Georgia doesn't tell us anything about his NFL outlook. The players he faces on Sundays will be better across the board. Some dominant college players have what it takes to make that jump. A lot of them don't. What I don't think you can do is look at a player's college stats in a vacuum, compare him to another collegiate player, and use that as proof that he's better. Tebow had better stats than Luck in a "stronger" SEC conference. What does that matter now?
