Top CB prospects for 2015

Soon after the 2014 NFL draft concluded, I released my "too-early" Big Board for the 2015 NFL draft, a ranking that includes players who will be underclassmen during the 2014 college football season. It goes without saying that these rankings are preliminary, as I have hundreds of hours of evaluation ahead on the 2015 class.

A couple of notes about the rankings below:

• This isn't a straight "Top 10" list, because I've split these between seniors and underclassmen. I think it's important to rank seniors alone, as those 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.

With those parameters in mind, here's an early look at the top cornerback prospects for 2015.

Top five senior cornerbacks

1. Ifo Ekpre-Olomu, Oregon Ducks: I think he would have been one of the first two corners taken in the 2014 draft had he come out. Ekpre-Olomu doesn't have elite size -- he's roughly 5-foot-10 and about 195 pounds -- but he makes up for it on tape, showing great instincts in coverage. He brings a physical nature when the play is in front of him, perhaps owing to his high school days as a two-way player who also starred at running back. Assuming he stays healthy, he's a first-round talent.
