As good as they've looked so far, that's just foolishness. It doesn't take a rocket scientist to figure it out. A brief look at another historically great NCAA team will tell us everything we need to know.
The 2001 Miami Hurricanes are widely touted as the greatest team in NCAA history. They rolled through their entire schedule, going unbeaten in the regular season and then beat Nebraska for the BCS championship.
Their roster included future NFL stars like Ed Reed, Jonathan Vilma, Andre Johnson, Clinton Portis, Jeremy Shockey, Kellen Winslow Jr., Vince Wilfork, and others.
As stacked as that team was, however, they'd never stand a chance against and NFL team. The answer is simple, and Pete Carroll says it best:
Carroll is completely right. There are All-American offensive and defensive linemen who would just be another average player in a rotation on NFL teams.
That 2001 Miami team was incredible. This year's Alabama team also looks pretty incredible. That Miami team was loaded with future NFL stars on both sides of the ball. This Alabama team will most likely produce many future NFL players as well.
But still, as good as they are, there are still areas in which Alabama simply can't match up with an NFL team.
As good as the 2001 Hurricanes were, remember that their QB was Ken Dorsey, who was a complete bust in the NFL. He was a 2-time Heisman finalist, but wasn't good enough for the NFL.
It's pretty similar to Mark Ingram, who was a beast for Alabama but has been a marginal player at best for the Saints.
That's typical, though. The Jaguars, as bad as they have been, have Blaine Gabbert at QB. He hasn't been anything special in the NFL, but he was a stud in college.
NFL rosters are chock full of guys who were amazing in college, from the top to the bottom of their rosters. There are All-conference players toiling on practice squads, and Heisman winners who went undrafted.
Alabama might be the best college team in the country by a long shot. But that's all they are. A college team. They'd get rolled by any NFL team. To think otherwise is... well, it's just not thinking at all.
