While former Gators cornerbacks Marcus Roberson and Loucheiz Purifoy garnered attention in draft gurus Todd McShay and Mel Kiper's initial first round mocks, it was Florida's most consistent -- and versatile -- defensive back last season who impressed during the 2014 NFL Scouting Combine.

Jaylen Watkins, an unheralded three-year starter with experience at safety, cornerback and nickel, ran a blistering 4.41 seconds official 40-yard dash, the fourth-fastest time among players at his position. Watkins also bench pressed 225 pounds 22 times, tied for tops among his positional peers.

Watkins' 52 tackles in 2013 were third-most on Florida and Tuesday's solid workout further highlighted his talent in the eyes of NFL scouts.

Meanwhile, Roberson and Purifoy both saw their stocks dip following poor performances in Indianapolis.

Purifoy, touted as an exceptional athlete and workout wonder, ran a stunningly-average 4.61 seconds 40-yard dash and managed just six reps on the bench press, fewest among all defensive backs. Roberson, who measured well (6'0", 191 lbs), also ran poorly (4.61) but did display solid leaping ability (37.5 inch vertical jump) and a nice 20-yard shuttle (4.08 seconds).

Both prospects will have a chance to redeem themselves at Florida's Pro Day on March 17, but with injury concerns (Roberson), off-the-field question marks (Purifoy), inconsistent tape (both prospects) and popular performances by other top defensive backs (see: Justin Gilbert, Jason Verrett, Bradley Roby), they could slip into the draft's middle rounds.
