Vertical Coverage - Long speed is average at best. When matched up with true burners, simply didn't have the wheels to stay on top of routes vertically. Does a good job of hand-fighting to maintain some leverage, but incredibly grabby as a result. No second gear to cover ground with the ball in the air. When he does manage to stay stride-for-stride with a receiver, plays the pocket extremely well and will compete all the way through the catch process. Uses his body well to eliminate space and body receivers to the boundary.
Fluidity/Agility - Tight in the hips and will struggle to recover if beaten off the line of scrimmage or out of the route break. Gives up way too much separation on in and out-breaking routes, and can't close the distance in recovery either. Footwork and transitions in man coverage are sluggish, not a gifted short-area athlete. In order to keep receivers from separation, turns into a penalty machine with plenty of holds and DPIs on his resume, both called and uncalled.
Ball Skills - Fails to get his head around to play the ball in the air vertically the vast majority of the time. This limits his ability to compete at the catch point down the field. Hakeem Butler ate him up in contested catch situations. Not a gifted leaper, but does show some ball awareness from off coverage and has good timing to contest throws in zone. Never going to be perceived as a ballhawk for sure, but he's not totally deficient in this area either.
Click-and-Close - Slow out of his pedal in off-man coverage, limiting his ability to close on throws underneath. Typically arrives in time to make a strong tackle, but doesn't contest a ton of windows. Not sure he's instinctive or explosive enough as an athlete to thrive in off-man.
Press Ability - Fairly patient in press position with a good, strong punch to stun receivers who are sluggish off the line. More explosive opponents with nuanced footwork got him to open up early in press, and he could not recover. Even when his technique is adequate, doesn't have the smooth hips to turn and open, often falling a step or two behind right off the line of scrimmage if he doesn't land a strike. Gets grabby early in the route as a result.
Route Recognition - I definitely wouldn't describe him as instinctive, but he isn't easily fooled by deceptive route combinations in zone coverage. Generally stays assignment sound and has a good feel for routes developing around him, even if his natural tools don't always allow him to make the plays he's processing. Will bite on double moves, was able to recover in some instances because he was so far off the receiver, but was burned by Kansas State twice.
Tackling - Very good tackler with ideal physicality for the position. Active all over the field and can make plays in space as well as around the box. Won't hesitate to lower a shoulder and deliver a big blow. Scraps for the football when closing for tackles underneath. Loves to blow up the screen game. Will occasionally get out-athleted in space and whiff on a stop.
Run Support - Big area of strength. Consistently flies downhill to play the run and will never hesitate to stick his nose in on the action. Sometimes a little too eager and bites inside, abandoning his perimeter run fill and forcing the safety to adjust on the fly.
Competitive Toughness - Coaches will love his willingness to do dirty work. Competes every play and hustles to get in on tackles in other zip codes. Plays with some confidence and will let receivers hear about it when he's bested them.
Athleticism/Size - Probably checks in around 5-foot-11, 190-195 pounds, so good size for a corner. Athleticism is average at best, a 4.5 40 would be a big win for him. I don't expect him to test well in the agilities either.
BEST TRAIT - Tackling/Run Defense
WORST TRAIT - Fluidity/Long Speed
RED FLAGS - None
A physical cornerback with plenty of experience (32 starts) and a competitive streak that will go a long way with coaches, Boyd has minimal upside, but could be an average starter in a zone-heavy scheme in the NFL. His lack of athleticism, long speed and short-area quickness will limit his versatility in the NFL, and I'm not sure he has the instincts or range to make sense at safety. Boyd can improve his press technique and get a little cleaner in his footwork, but right now he looks like a day three player who will need to make his way on special teams before earning the chance to start.
