Many times, drawing comparison to current NFL stars is the best way to describe the top collegiate prospects.
These are the top three runners in the 2012 draft class and the players they remind me of at the pro ranks.
Trent Richardson—Marshawn Lynch
Alabama's star runner brings everything any head coach would ever want to the running back position.
Although he's 5'11'' and weighs 215 pounds, Richardson is more than a straight-forward, between-the-tackles runner.
He definitely runs with a punishing style that can lead to big chunks of yardage on inside dive plays, but he has deceptive acceleration around the outside and agility in the open field. He loves making defenders miss but worked tirelessly to build a ridiculous amount of muscle to his frame that has made him welcome contact.
Seattle Seahawks running back Marshawn Lynch is the closest comparison in the NFL. The similarities are striking.
Lynch is also listed at 5'11'' and 215 and the way he and Richardson run the football is nearly identical.
Richardson is probably a better overall athlete and possesses more open-field speed, but other than that, they're extremely alike.
Lamar Miller—Ryan Mathews
Miller runs similarly to Mathews—their patience and fluidity are great for young tailbacks.
The Chargers' runner is about 6'0'' and 220 pounds, while the Miami Hurricanes star is 5'11'' and a shade above 210.
Miller is no novelty, situational runner—he certainly demonstrated the capability of being a three-down back during his collegiate career.
Although he's most effective on pitches outside the tackle, he can pick up valuable yardage up the middle. When he reaches the second level, he calmly shifts directions and accelerates past linebackers.
A lot of the same can be said for the multidimensional Mathews, who increased his total yards and yards per carry in 2011.
The redshirt sophomore hasn't proved to be a great out-of-the-backfield receiver, but with his great athleticism and speed his NFL coach will do whatever he can to get Miller the ball in space.
Chris Polk—DeAngelo Williams
Polk is a few inches taller than the 5'9'' Williams, but they both float between 215 and 220 pounds and have the same style of running the football.
Their athletic ability and nasty jump cuts sneak up on you while they display no fear when facing bigger defenders. And while neither guy is labeled a "home-run hitter," if they build up speed around the edge, they can break a long run.
Polk caught 31 passes in 2011 and certainly knows how to set up blockers on the screen play, which is a huge plus as he enters the draft.
Williams runs a little lower, mainly because he's shorter, and they both are equally as effective on inside and outside plays.
I love Polk's potential as an every-down back at the next level, although, like Williams he could flourish with a complementary tailback.
