So you would have passed on Randy Moss, Brian Westbrook, Terrance Mcgee, Jeremiah Trotter, Darren Sharper, Kurt Warner, Jimmy Smith, Steve McNair, Jerry Rice, Andre Reed, Matt Birk, Marcellus Wiley, Donald Driver, rashean Mathis, Dexter Coakley, Wayne Chrebet, Jerry Azumah, Adam Timmerman, Adam Vinatieri, Terrel Owens, Michael Strahan, Brian Finneran, Rodney Harrison, Chad Pennington, and Troy Brown? And trust me, there are many more.
And it might surprise you to know that 10.27% of the player in the NFL came from, wait for it.... wait for it... Division 1-AA.
Edit: BTW you always always ALWAYS look at the player, not the school, not the combine numbers (I really don't give a flying if someone can run 40 yards 0.02 seconds faster than the next guy).
Did he dominate the players lined up across from him? And does he fit in your system? That is what matters.
