DRAFT TRACKER 2015

Nose tackle with desired height, weight and speed. Flashes talent necessary to project a ceiling as a dominant run stuffer best suited for a 3-4 defense. Phillips' ability to eat up blocks should help him earn a high grade, but it's his potential as a big athlete with above-average range for the position that could turn him into a Pro Bowl nose.

Long-strider with vertical ability to change a game and the catch radius and body control to make the difficult look easy. However, Green-Beckham struggles against physical cornerbacks, and is raw as a route runner with poor instincts when it comes to getting open. It's easy to bet on the traits when a receiver has high football character and is a willing worker, but teams could pass on the traits early in the draft due to his perceived lack of work ethic and overall character.

Williams is a competitive player with all the football character you want and NFL power to match. When he gets defenders lined up in his sweet spot, he can drive them out of the play. Winning with guile and toughness over skill, Williams' lack of functional athleticism is a concern and might be a catalyst for a move inside to guard.

Grissom is still very raw and has plenty of football to learn. Some scouts believe he will test well and improve his draft standing beyond where the tape says it should be. He's not a plus pass rusher, but has draftable traits and an untapped upside. His biggest concern could be finding a true position fit.

Thompson has NFL size and flashes NFL potential, but he doesn't play with the consistency or effort that NFL scouts want to see from him. There will be teams that drop his grade due to football character, but tackles that have traits and upside usually get drafted earlier than their draft grades call for.

A newly converted tight end who was a short-yardage specialist and red-zone brute for the Sooners as a quarterback. Bell was looked over by scouting community during the regular season, but he has flashed sure hands and shown improvement as a blocker and could have an NFL future if a team is willing to be patient with him.

Old-school blocking back who will have a hit or two each game that wows the crowd and gets his teammates fired up. He often charges in head-first and with a lowered head, so his success rate can vary greatly from game to game. Lack of pass-catching background hurts his chances.

His combine speed will have people talking, as will his size and the classroom efforts that have helped him earn Academic All-Big 12 honors for four straight years. Unfortunately, his lack of cover talent, physicality and ball skills could make it tough for him to get much of a look from pro teams.
