On Tuesday, Mel Kiper Jr. released his top 2015 QB prospects.

The list is building on his 2015 Too-Early Big Board, going position by position. But for these breakdowns, Kiper noted:

This isn't a straight top 10 QB list because I've split them into seniors and underclassmen. I think it's important to rank seniors alone since they are the only players I can guarantee will be a part of the 2015 NFL draft process.

In some instances I've included more than 10 players; if two or three guys are extremely close on my board, I simply tacked on the names.

But no conference is as well represented on the quarterback list as the Pac-12, which snagged five of the 11 spots. The SEC and Big Ten have two on the list, while the ACC and Big 12 each have one QB represented. Of the five Pac-12 quarterbacks, two are seniors and three are underclassmen.
