Lamar might have looked better in college than Vince but he played for Louisville in a much easier conference.
He didn't just look better. He was better. By a lot. Go check his numbers. Off the charts.
I'm not a big believer in conferences telling me how good a player is. I believe what I see. For example, the University of Hawaii doesn't produce many NFL players, especially since June Jones left in 2009, but I know NFL talent when I see it. Like WR John Ursua. He will play on Sundays if he can stay healthy.
Yes the SEC produces the lion's share of NFL players, because the best high school players in the country flock there, but a good player is a good player.
