18. Isiah Pacheco – 4.37
Pacheco was a high school quarterback before he evolved into a college running back. While it took some time to adapt to his new position, Rutgers has reaped the rewards. That’s because he was impressive for the Scarlet Knights and earned an invitation to the NFL Combine.

A 40-yard dash time of 4.37 seconds is nothing to sneer at. Pacheco is a fast player with heavy links to the Denver Broncos. He will likely be a late draft pick or even miss selection. But after working out in Denver, he will probably fight for a place on their roster (via 247 Sports).
