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. – Lance Zierlein

Compact running back with power in his lower body to break tackles and extend runs, but he’s not a chain-moving power runner with a desire to punish tacklers. Tape shows borderline athletic ability as a pro with little to no value as a third-down back, which limits his draft value. – Lance Zierlein

One of the most explosive runners in college football during his time at Miami, Johnson doesn’t need much of a crease to make defenses pay. His explosive quickness and elusiveness should help him adapt quickly to NFL speed and his feel and courage as a one-cut runner should earn him instant playing time. Johnson’s lack of protection skills and his injury concerns could force him into a committee situation. – Lance Zierlein

Johnson lacks the short-area quickness to be a consistently effective every-down running back, but he has good size, speed and hands so he can’t just be dismissed. He doesn’t run routes well enough and isn’t sudden enough to be a wide receiver, so he might have to be a third-down back with kick-return potential. – Lance Zierlein

One-speed running back with some weight behind his pads, but not enough explosive power to offset his lack of burst and overall athleticism. Could struggle to find a home as an NFL running back and might need to take a look at playing fullback. – Lance Zierlein

Lacks elusiveness and doesn’t carry enough power behind his pads to create any intrigue. Couldn’t even get to 100 carries in a single season while in college and unlikely to be able to break into rotation in the pros. – Lance Zierlein

Scat back with exceptional foot quickness and athleticism. He lacks the size and play strength to handle the rigors of being a first down running back. Heard can mismatch linebackers out of the backfield in the passing game and can create explosive plays as a runner if his blocking is decent. His value to a team will depend directly on scheme. – Lance Zierlein

Undersized runner with a big back’s fearlessness. Hart is a gritty, determined player who fought his way back from two injuries to the same knee and a lack of playing time at Alabama before transferring. He was highly productive in his one year at Colorado State, but could have a hard time making a roster due to his lack of size and pro-caliber quickness. – Lance Zierlein

The rehab work and NFL Scouting Combine medicals will be extremely important for Gurley’s draft stock as teams assess his potential durability as an NFL running back. He played less than 40 percent of his team’s offensive snaps over the last three years, so there is plenty of tread still on the tires. Has the talent to be a top-five NFL running back, but ACL tear clouds the short-term picture. – Lance Zierlein

Angular, talented open-field runner who combines outstanding burst with a long stride to gain separation and hit the home run. He won’t be able to outrun NFL defenders like he did in college and must develop more feel between the tackles. Gordon shines when his track runs over tackle or around the end and can put a defense to sleep around the corner. Not trustworthy enough to be a three-down back, but his pass-catching improved enough to utilize him out of backfield as a receiver. – Lance Zierlein
