DRAFT TRACKER 2015

Strong-side 3-4 outside linebacker with the physical traits and above-average potential to set the edge or spill runs wide to an early demise. Fowler is a competitive pass rusher getting by on athleticism and inside moves right now, but has a Pro Bowl ceiling with double-digit sack potential if he takes coaching and addresses his rush technique.

An elite-level tackle when he exited the high school ranks, Humphries relies on his superior athleticism and fist-fight mentality rather than an improved skill set and steady technique. He might always have an issue with being a leaner, but his hand placement should improve with more work and coaching. When he improves in that area, he could become a solid NFL starter on the left side.

Watch the tape and his intelligence and toughness immediately stand out. Riggs is a student of the game and displays a field awareness that secondary coaches will covet. The biggest issue for Riggs is that his size might cause some teams to marginalize him and he doesn't have much productivity to hang his hat on. Riggs seems like a perfect fit as a nickel cornerback who can help in run support and who can compete against receivers of all sizes and speeds.

While Shaw played boundary corner, slot corner and safety at USC, concerns over his athleticism and speed could limit him to zone-cornerback status as a pro. Shaw seems to go along for the ride while on field rather than operate with a voracious appetite to make plays. He's not physical enough to play in the box, so he will likely have to be a Cover-2 cornerback or free safety as a pro.

A competitive, move tight end with an ability to make contested catches that other tight ends will struggle with. While he won't look as natural and fluid as you would expect, the tape shows a guy who can get separation in space. Has traits to be a quality player who brings diversity and toughness to an offense.

Athletic interior lineman with an ability to become a more disruptive penetrator with more coaching and improved technique. He will probably be targeted by one-gap, upfield defenses. His maturity level will be questioned at the NFL Scouting Combine and beyond. The way he handled his situation at Florida could sink his draft prospects, but it shouldn't sink his chance to make a team and become an NFL backup.

Has very good athleticism for a big running back and is a physical pile-mover who is difficult to stop for negative yardage. Unfortunately, Jones lacks the instincts and vision to fully maximize his physical tools. Jones could become the physical member of a running-back-by-committee approach, with upside as a third-down option.

Converted center who has taken reps at tackle and started an entire season at guard. Limited phone-booth mauler with above-average upper-body strength and toughness at the point of attack to play in the NFL. His physical limitations could hurt his draft standing, but his functional strength and potential to swing between center and guard give him a decent shot to make it in the league.

Brown has the pure size to block out the sun, and unlike some players with his bulk, he knows how to use it. He can plow holes as a run blocker, but can only play right guard in a power scheme. His lack of playing experience and conditioning concerns could hurt his draft stock.

Teams will be forced to draft Trail on projection rather than tape. While his production looks good on paper, Trail never stands out as a dominant force. He failed to flash at the Senior Bowl as a defensive player but took some reps near the goal line as a tight end, which could be his best chance to make a team and stick in the league.

Heady player with potential position versatility, but lacking an area where he truly excels. His foot quickness and movement skill will appeal to zone-scheme teams but he must improve his strength and ability in pass protection if he wants to be anything more than a backup.

Played right tackle at Boston College, but is better suited to be a guard due to his power and lack of foot quickness. Silberman has some physical limitations, but he has the balance and natural power that should intrigue NFL teams.

Versatile linebacker with good play speed and a motor that teams look for. While Ball's play clearly improved from 2013 to 2014, his physical issues will be tough to overcome by draft day. He overcame losing both of his parents before the age of 10 as well as brain surgery in 2011, so he's no stranger to adversity and perseverance. Ball might have to attempt to beat the odds once again and make a roster via the undrafted-free-agent route.

Early entrant to the draft who has NFL-ready size, but is lacking NFL-caliber strength. Moore doesn't play with enough bend to be able to mitigate those strength issues with technique, and his feet are very average in the run game.
