My alma mater, NCCU is FCS but of course we play some of those early season money games. From guys I either saw or heard anecdotes from players/coaches/fans
No order (interestingly enough all WRs)
1. Ramses Barden - Cal Poly (2008) He only had 3 catches and 2 TDs, but brehs were saying he was too big and physical. 6'6 230 WR. 2009 3rd rd pick for the Giants
2. Mohamed Sanu - Rutgers (2011) I remember watching that game on ESPN U, he had 6 or 7 catches, but like Barden was too big and physical.
3. Corey Davis - Western Michigan (2016) 7 catches 150 yds 3TD. Titans 1st rd pick this year
Bonus - RB Tarik Cohen - NC A&T (got drafted by the Bears this year, a beast)
