Is cornerback Big 12's strongest position?

Mel Kiper Jr. is continuing his look through the top prospects at each position in advance of next year's NFL draft, and his list of the top 10 cornerbacks includes four players from the Big 12.

It was a deep position last year, but could it be the Big 12's deepest and best position in 2013? We'll see how the new quarterbacks develop, but these guys won't make it easy on 'em.

Oklahoma's Aaron Colvin tops the list from the Big 12Insider, showing up as Kiper's No. 4 overall cornerback. He's moved positions in the secondary throughout his career, and that versatility really impressed Kiper. He broke up 14 passes last year and also came up and made a pair of sacks.

TCU's Jason Verrett was my pick as the Big 12's best cover man a year ago and showed up as Kiper's No. 5. His performance in slowing down Geno Smith drew Kiper's attention, and Verrett was one of just a handful of guys to pick off the West Virginia quarterback.

Justin Gilbert's eye-popping physical attributes have him at No. 6. He's got a lot of potential to rise on this list. He had a really poor 2012 after a promising sophomore season in 2011. He can be a lot better than he was last year. If he proves that, he'll jump up this list.

Texas' Quandre Diggs is No. 7, and despite being smaller than a lot of these guys, he's one of the league's most instinctive players. You saw that when he made an impact immediately as a true freshman. I wouldn't look beyond his teammate, Carrington Byndom, cracking this list by season's end, too.
