Glenn did not set the world on fire during agility tests at the 2015 NFL Scouting Combine, where he was clocked at a pedestrian-like 4.64-second 40-yard dash that was the third-slowest for any cornerback in Indianapolis. He could not disprove the scouts’ feelings that he lacked strength, as a right hand injury prevented him from participating in the bench press test.
Glenn did show loose hips in the shuttle drills and impressive leaping ability during the jump tests, but his numbers translate better to those of a strong safety, rather than as a cornerback. The problem with that: he’s just 179 pounds with little room for further body growth and development.
The Knights red-shirt sophomore’s success on the field is due to his above-average football instincts, as he is very quick to break down and diagnose the action coming out of the backfield. He has a very good feel for anticipating the route’s progression and has that split-second decision-making process that lets him get a quick jump on the ball.
If Glenn was 200 pounds, he would be a nice free safety candidate, as he shows very good feel for the switch-offs when used in zone coverage, as he can immediately locate the targets coming into his area, along with veteran-like instincts that prevent him from biting on the receiver’s attempts at executing double moves.
Even with his marginal speed, Glenn displays smooth movement skills, as he has the loose hips needed to quickly open, turn and change direction. There is no wasted motion or extra steps taken by this defensive back at the top of his backpedal when transitioning forward, and while he can be beaten on deep patterns he has very good short-area closing quickness.
In the short-to-intermediate areas, Glenn has the ability to mirror receivers when aligned in press-man coverage but is not going to deliver a strong hand jolt to take his opponent off-balanced. He shows good urgency to cut down separation when the ball is in the air and his nine interceptions and 26 pass deflections prove that he can make plays on the ball in flight. He also shows the ability to quickly transition and regain his balance when a receiver eats up his cushion.
Glenn’s recovery speed is called into question when he’s caught in the trail position. He does demonstrate above-average hands and playmaking ability as a pass thief, doing a nice job of utilizing the sidelines and boundaries to squeeze the receiver when he is able to stay with his coverage assignment on deep patterns, but I question that he will ever have the valid speed to do this vs. NFL caliber wideouts.
It is definite that Glenn “lacks sand in his pants” playing vs. the run, as he often struggles to shed blocks playing in the box and even bigger and more physical receivers can pin him in the second level. What he does best is slip off those blocks in the open field to make plays, as he has a good concept for taking angles in pursuit. He will never be a classic wrap-up/drag-down tackler, as he rarely has success taking bigger ball carriers off their feet, reverting to “ankle-biting” in attempts to stall until help arrives.
