Big 12 players to watch at NFL combine

Players and media are arriving in Indianapolis for the NFL's annual scouting combine. Specialists, offensive linemen and tight ends comprise the first group with interviews and weight-room work starting on Thursday, followed by on-field workouts and drills set to begin on Friday.

Here are five former Big 12 players who have a chance to improve their stock over the next few days. You can find the full list of Big 12 participants here.

Needs to impress: Dorial Green-Beckham, receiver, Oklahoma. DGB’s talent is not in question. On the field, he looks like a difference-maker with his combination of size, speed and athleticism. But plenty of questions about his off-the-field troubles linger over his physical talent, making it easy for NFL scouts and coaches to look elsewhere. If Green-Beckham can start to ease those concerns with a strong showing in the interview rooms,then dazzle on the turf at Lucas Oil Stadium, it would help his stock tremendously.

Needs to run well in the 40: Kevin White, receiver, West Virginia. He is in a battle to be the first receiver off the board. The Biletnikoff Award finalist will likely be a high draft pick either way, but if he runs a fast time in the 40-yard dash, erasing any questions about his speed, his stock could really skyrocket. At 6-foot-3 and 210 pounds with terrific ball skills and the ability to make plays after the catch, White looks like a No. 1 receiver in the making.

Has the most to gain: Bryce Petty, quarterback, Baylor. As the fourth-ranked quarterback by draft guru Mel Kiper, Petty isn’t expected to be given the immediate reins of an NFL franchise during draft weekend. But Baylor's record-setter could really help himself with a strong combine that shows off his accuracy and arm strength. He should have no problem intriguing teams with his intelligence and confidence in the interview room.

Can maintain momentum: Kevin White, cornerback, TCU. After a solid showing at the Senior Bowl, White could continue the momentum at the combine. The on-field work for the cornerbacks on Monday could be a critical time for the former Horned Frogs cornerback. If his on-field workout shows he is fluid enough to handle NFL slot receivers, it would help White's stock tremendously.

Overlooked player to keep an eye on: Blake Bell, tight end, Oklahoma. Bell is right alongside Petty as one of the former Big 12 players who could gain plenty with a strong combine. At this time a year ago, Bell was in the early stages of a transition from quarterback to tight end. His limited experience and raw ability is intriguing for NFL teams thanks to his athleticism at 6-foot-6 and245 pounds. The combine is his opportunity to show NFL teams he can be an asset with high upside if they decide to take a chance on him in the later rounds.
