I always love the college people saying a college team could beat a pro team. I remember somebody saying it about the Miami Heat in a game versus UNLV when UNLV was undefeated and Miami was like 0-21. It was an actual huge topic on sports radio.
I had friends telling me this over and over and I said, "Look.... UNLV may at BEST end up with 3 of those guys being good NBA players, and the rest won't even make an NBA roster. The Heat are a team of 12 guys who all would be in the starting lineup for UNLV right now, and possibly would even be their best player." It was quite a discussion point. A local radio guy said everybody on UNLV would be an NBA star. So my friends claimed I was wrong. What happened? Larry Johnson was an NBA star for a couple of years, but his spine wore out quickly. Stacey Augmon who was supposed to be better than Pippen didn't even ever get to be as good as Derrick McKey, and I believe the only other to make the league was George Ackles, and he just flat out sucked and only got into the NBA because he was a tall space filler. So there you go... 3 NBA players, and one of them good. Whereas the Heat had 12 NBA players, probably 2 as good as LJ, and 10 better than the rest of the UNLV roster. In fact that UNLV team went on to get beat by Duke, who had I believe 3 NBA players too.... Grant Hill who was really good for a bit, Christian Laettner who was ok, and Thomas Hill who never did anything.
Alabama would be amazing if they got 9 guys off of their current roster into the NFL. You'll see schools that have 15-20 guys in the league, but they didn't all play together. There is overlap and such. There is no college team that could even keep it competitive for a quarter with any NFL team.
People like to use the AAA team beating their major league team in an exhibition as an example because it happens all the time. In those cases 9 out of 10 times it is the AAA team vs. the AAA team. The major league team calls up a AAA pitcher for the day and lets him pitch against his own teammates, and the starters play about 3 innings. Plus that is a game that is all dependent on pitching and tempo. Football is so fast that no college team could hang. I'd like to see it happen just for fun sometime to shut everybody up, but of course it never will.
