Phillip Dorsett, WR, Miami (Fla.)
Teammate Artie Burns certainly has a case of his own, but Dorsett is a tick faster as a sprinter and, on the field, as a wide receiver. He's reportedly run as fast as a 4.29-second 40-yard dash, posted a 10.58-second time in the 100 meters last month and could be primed for a breakout year if he can limit his drops.
