All the Elite 11 QBs going back to 1999.
Lot of guys who have ended up great. Lot of guys who were ok. Lot of guys who I have never heard of. Without researching, seems to be 50/50 if a guy has a decent career. And way smaller odds he become a superstar (10%?)
Best classes look to be (guys who I remember as starters)
2005 - J Freeman, C Hawkins, J Locker, M Mustain, J Snead, M Stafford, T Tebow, I Williams
2007 - D Crist, B Gabbert, M Glennon, J Harris, L Jones, A Luck, EJ Manuel, S Renfree
2008 - T Body, G Gilbert, A Maxwell, AJ McCarron, Z Mettenburger, A Murray, B Renner, T Savage, G Smith
Others of note:
Harrison Beck's 2004 class had J Crompton, C Daniel, M Sanchez, W Tuitama
Johnny Stanton's 2012 clad had J Dobbs, C Hackenburg, M Zaire (and it still pretty early to since most are entering their RS Soph years)
