Auburn running back Onterio McCalebb blew scouts away at the 2013 NFL Scouting Combine when he ran an official 4.34-second 40-yard dash. 

Per the Tennessean's Jim Wyatt:

#Titans RB Chris Johnson's record time of 4.24 is still safe. Onterrio McCalebb's official time: 4.34. So much for the 4.21

— Jim Wyatt (@jwyattsports) February 24, 2013

McCalebb's unofficial time was 4.21, which would have broke the 2008 mark of 4.24 seconds set by Tennessee Titans running back Chris Johnson, who is paying close attention to the proceedings in Indianapolis this year.

Listen 4.21 thats childish

McCalebb also posted a time of 4.27 in his first run, proving that this time wasn't a fluke.

NFL Media PR posted this on Twitter after McCalebb's run:

Via NFL Network's camera technology, it appears WR Goodwin was slightly faster than RB McCalebb. Goodwin ran a 4.27 40-yard #NFLCombine

McCalebb is an explosive athlete, but he's also an extremely small player at 5'10" and 168 pounds.

He set an Auburn record with 8.5 yards per carry in 2010, and throughout his four-year career with the Tigers, he rushed for 2,586 yards and 24 touchdowns on 406 carries and caught 63 passes for 620 yards and three touchdowns.

McCalebb is also an accomplished special teams player. He tallied 1,360 yards and two touchdowns on kickoff returns in his four years at Auburn.

His pure speed will surely have teams drooling over his potential to make game-changing plays at the next level, but his lack of size will certainly keep him from dramatically shooting up draft boards.

Speed isn't the only quality McCalebb brings to the table, though. He is extremely agile, quick to change direction and is a skilled receiver.

He could end up being used more as a receiver out of the backfield than as a pure runner, much like what the Green Bay Packers did this past year with Randall Cobb.

NFL players McCalebb might be compared to are Darren Sproles and Dexter McCluster.

Sproles is 5'6" and 190 pounds, while McCluster is 5'8" and 170 pounds. Both of them have managed to make a positive impact in the NFL, so it's not out of the question to believe McCalebb is capable of doing the same.

One thing is for certain: This man is fast.

The NFL is always looking for men who can score on any given play. He'll get a chance to prove his worth in 2013, and if he stays healthy, McCalebb could become a dynamic playmaker at the next level.
