Like his other local counterpart, Kevin White, Diggs is a bit undersized. That doesn't seem likely to stop him, though, as he posted a 4.57 40 from the Combine. Diggs played a lot of nickel at Texas, which could be beneficial for the Cowboys if they move Orlando Scandrick out of the slot in 2015. Even with good workout numbers, it's reasonable to expect Diggs to be there when Dallas is picking between the fourth and seventh rounds.

Byron Jones, Connecticut
A workout warrior if ever there was one. Jones wasn't highly-regarded going into the Combine, but he changed all that around with an event-record broad jump of 147 inches -- which is 12 feet, 3 inches. He also posted an outstanding 44.5-inch vertical. Expect to hear his name more often as the draft nears.
Quinten Rollins, Miami-Ohio
His Combine numbers aren't eye-popping, but he promises to be one of the most interesting prospects to come out of this draft. Rollins was a basketball player until his senior year of college, and he wound up leading the MAC in interceptions with seven and was named MAC Defensive Player of the Year. As of yet it's hard to peg his draft status, but some projections have him going as early as the first round.

Kevin White, TCU
Much like Darby, his measurable -- 5-9, 183 pounds -- aren't going to make him stand out on the draft board. His on-field performance speaks for itself, though. In addition to locking down his opposition's best receivers at TCU, he had a fantastic outing at the Senior Bowl in January. The Cowboys could add this valuable defender and special teamer in the second or third round.

Widely considered to be the top corner in this draft class, up until he tore his ACL in bowl practices. Given the timeline for ACL recovery, he’s likely not going to be ready to play until 2016, which doesn’t help a team with an immediate need, like the Cowboys. Still, his injury could make it possible to attain a first-round talent with the No. 60 pick.

Ronald Darby, Florida State
If Williams' stock has been dropping, then his teammate is picking up the slack. Darby wowed onlookers with a 4.38 dash and a 41.5-inch vertical. He's just 5-11, which is slightly concerning for the Cowboys, given the size of their other corners. But there's no denying his ability.

Jalen Collins, LSU
Few of the several hundred Combine invitees had a better showing than Collins. He already raised eyebrows with his 6-1, 203-pound frame, but then he went out and ran a 4.48-second 40. Most will acknowledge that he’s raw, but he might have pushed himself into the first round on athleticism alone.

P.J. Williams, Florida State
The post-Combine buzz is going to be that Williams was a disappointment because he ran a 4.57 40-yard dash. Speed is certainly important to the position, but it's worth remembering that he was Florida State's best cover corner during an enormously successful stretch. His size alone, at 6-0, 194 pounds, makes him an appealing option.

Trae Waynes, Michigan State
Regarded by many as the top corner in this draft, and he didn't do anything to dispel that notion when he clocked a 4.35 40 time in Indianapolis. It seems unlikely he'd fall as far as No. 27, but this corner class doesn't seem to have a top-10 lock, so anything is possible.

Marcus Peters, Washington
This seems like an incredibly realistic scenario for the Cowboys, given that Peters' Combine numbers don't jump off the page, and he had well-documented problems with his coaching staff in college. He still has top-notch talent, though, and the knocks against him could push him toward the end of the first round.
