Bradley Roby was always considered one of the fastest ― if not the fastest — guys on Ohio State's football team. Today, he went out and proved he has some wheels underneath him.

The former Ohio State cornerback posted an official time of 4.39 in the 40 yard dash. Oklahoma State's Justin Gilbert posted the fastest cornerback time with a 4.37.

In the lead-up to the sprint, draft analyst Mike Mayock blamed Roby's poor performance against Wisconsin on "poor eye discipline," while Deion Sanders pinned Roby's struggles on the defensive game plan.

Many analysts expect Roby to be the first Buckeye taken in the 2014 NFL draft.
