I'm not going to be remotely surprised if the Cowboys pick two cornerbacks when this draft finally starts, so I'm definitely trying to identify valuable guys who can be taken in the later rounds. This might be too late for Gaines, but he'd be another talented corner and he could improve the tackling in the Dallas secondary.

Gerod Holliman, S, Louisville
Holliman led the nation in picks with 14 and added 17 passes defended, securing himself the Thorpe Award. The fact that he's considered a mid-round pick despite those accomplishments is telling, but he certainly knows how to go after the ball. You probably wouldn't want Holliman competing for playing time right away, but those ball skills make him interesting.

Gabe Wright, DT, Auburn
Wright's numbers dropped in his final season at Auburn, dropping from 31 tackles and 8.5 sacks as a junior to 24 tackles and 4.5 sacks as a senior. Still, he's got the benefit of starting experience in the SEC and no shortage of talent. He functions better as a pass rusher than a run stuffer – but that's exactly what the Cowboys need.

Ty Montgomery, WR, Stanford
Much like the running back situation, there's no shortage of options to find a Dwayne Harris-type receiver in this draft. Montgomery should hang around until the middle rounds, but he's got 4.50 speed and he was named all-conference as a kick returner for the Cardinal.

Lynden Trail, DE/OLB Norfolk State
No one really seems to know what to do with Trail, as he played both defensive end and linebacker in Norfolk State's multiple front. There's also speculation that he might be best suited for tight end. Regardless, he's 6-7, 269 pounds and has shown flashes of incredible athleticism. He's a guy you'd draft based on upside, but that upside could be quite high.

Markus Golden, DE, Missouri
He wasn't quite the same caliber of pass rushing phenom as Missouri counterparts Aldon Smith, Michael Sam and Shane Ray, but Golden put together two quality seasons during the Tigers' back-to-back runs as SEC East champions. He's good against the run, as he made 78 tackles last fall, and he could begin as the No. 4 man in the Cowboys' defensive end rotation.

David Johnson, RB, Northern Iowa
You can factor a quality running back for nearly every round of this year's draft – that's how deep this class is. Johnson is an under-the-radar favorite for a lot of draftniks, after tallying 2,500 all-purpose yards last season and participating in the 2015 Senior Bowl. The Cowboys want physicality, and Johnson is a load at 6-0, 224 pounds.

Sean Mannion, QB, Oregon State
Mannion looks the part of an NFL quarterback perhaps moreso than any of this year's prospects, but there are plenty of concerns about his mechanics and athleticism. If the Cowboys don't grab Bryce Petty earlier on, Mannion might be their next-best bet to draft a developmental quarterback.

Ben Heeney, LB, Kansas
Dallas took Anthony Hitchens at No. 119 in the fourth round last year, and he excelled at all three linebacker spots. Heeney is a similar type of player – not all that physically impressive, but he comes with a high motor. He made 335 tackles in three years as a starter for the Jayhawks. The Cowboys wouldn't need Heeney to compete for a starting linebacker job, but he'd be fantastic for depth and special teams play.

Daryl Williams, OT, Oklahoma
The Cowboys need a swing tackle, and the fourth round seems like a solid place to find value -- that's where they found Doug Free eight years ago. The right set of circumstances could see them select one earlier, but ideally they could address their more immediate defensive needs early on. A guy like Williams would be great for the overall depth of the line, and a good price.
