I can find way more busts who put up big numbers and made All American teams in college than you can find guys who became stars in the NFL.
There is NO CORRELATION to college performance and NFL success. You will find just as many NFL stars who never made an all-american or all-conference team as you will find those who do.
You do understand "finding busts" is a galactic logical fail, right? (oh wait, it's you, why would I expect understanding?) I just put forth where every NFL offensive skill position record (QB, RB, WR & TE) was held by a college stud at their respective position. ALL OF THEM. The only way NOT to call that a correlation is to not understand what "correlation" even means.
Now again, (and by again I mean I've said this already) success in college does not in any way
guarantee success but that doesn't preclude correlation. So, let's go deeper.
Top 10 QB's since 1990 (that position has changed a lot so, with all due respect to, say, Fran Tarkenton, I'm wanting to keep this one more modern)
Peyton Manning-no explanation needed
Favre-nothing special
Drew Brees- Big10 POTYx2, over 11k yards
Brady- nothing special
Eli Manning-no explanation needed
Ben Roethlisberger-MAC OPOTY, over 10k
Drew Bledsoe-Pac10 OPOTY
Philip Rivers-ACC POTY
Carson Palmer-Heisman
Kerry Collins-AA
So basically 8 of 10 managed at least a conference Offensive Player Of The Year honor. No correlation huh?
Rushing
Emmitt Smith-AA
Walter Payton-AA
Barry Sanders-Heisman
Curtis Martin-nothing special
LaDainian Tomlinson-AA
Jerome Bettis*
Eric Dickerson-AA
Tony Dorsett-Heisman
Frank Gore*
Jim Brown-AA
First check out that 7 of 10 are
at least AA if not Heisman winners. *Bettis and Gore are interesting in that neither even had 350 career attempts, 337 and 348 respectively. (to put that in perspective Henry had 395 just last season alone) Still both put up over 1900 yards on those carries and both had a better ypc than Henry did on his way to winning the Heisman. Upshot- from the RB position the only true outlier is Curtis Martin. Yeah, strong correlation between NFL career yardage leaders and success in college.
