After wowing the 2013 NFL Scouting Combine with an unofficial 4.21 and an official 4.34 dash in Indianapolis, many were definitely fascinated to see whether the running back would be able to produce similar numbers again or whether the combine was simply a one-off.
Well, with an unofficial 4.29, a 37.0 inch vertical leap and a 123.0 inch broad jump, the reports on McCalebb were no doubt confirmed to be true.
The kid is incredibly fast, and he is pretty good at football too.
Having set an Auburn record with an average 8.5 yards per carry in 2010, McCalebb has produced incredible numbers in throughout his four years at the school.
He totaled over 2,500 rushing yards and 27 total touchdowns for the offense, but also netted over 1,350 returning yards and two touchdowns on special teams. Which, given his speed and agility, makes perfect sense for the running back to continue to do once in the NFL.
Yet, the biggest question now is where McCalebb will be drafted, having chalked up some impressive times throughout his two scouting appearances.
NFL Draft Scout currently ranks him as the 22nd-best running back in the class this year and just outside the seventh round in terms of draft selection. That might seem bizarre given the numbers and achievements we've discussed, but it's important to remember McCalebb's size and ability to become an effective NFL running back.
Standing at just 5'6" and 190 pounds, the Tigers' running back is an incredibly small athlete—even for a running back. Big questions exist about whether he would be able to take a beating between the tackles and not lose the football—which is what would be expected of him as a running back—which is likely to impact his draft stock in 2013.
Sure, he's got excellent hands, agility and obviously speed in him, but his size will definitely keep him from rising up the draft boards this year as a result.
He's an excellent special-teamer, who teams could use out of the backfield like the Green Bay Packers did Randall Cobb this season. But as far as regulation carries go, it's hard to see McCalebb being anything other than a special-teamer, return-specialist and read-option player to try and spread out an opponents' defense for other players.
McCalebb could be dynamic if given the chance, but his size will keep those doubts lingering long enough for coaches to pass on him up until the final round when someone takes a chance and picks him.
That could turn out to be one of the most potent late-round signings we've seen in recent history, or it might just end up being another body to fill a squad.
It all depends on how a team chooses to use him in 2013.
How would you rate Onterio McCalebb's 2013 draft stock?
