Run Defense - Plays with good leverage and extension but I would not consider him overly stout at the point of attack, especially for what is expected from him stylistically given his overall profile. Offers very little in terms of penetration skills. Will work himself out of run fits by spinning off contact.
Pass Rush - Not overly explosive and is fairly tight throughout his frame. Labors to work his hips around edges. Slow burn with his attack, often without a plan and resolves to an attempt to play through the block. Way too many extra steps working around the arc. Lacks any sort of nuanced approach.
Burst - Limited burst out of his stance and doesn’t put much stress on offensive lineman's ability to redirect and mirror. Works hard in pursuit but range is modest. Heavy legs and long strides. Not a great snap anticipator.
Effort - No concerns in this area. Works hard on every snap to fulfill his assignments and get after the football. Lacks technique in his counters but doesn’t stop working when his initial rush stalls. Gives tremendous effort in pursuit.
Hand Technique - Has decent length and heavy hands that allow him to work into the frame of blockers. Hand swipes and counters are a bit elongated and he doesn’t have wide-ranging moves to disengage. Everything needs to happen quicker.
Flexibility - Tightly wound hips make it difficult for him to work his hips through contact and turn corners. Lack of lateral mobility limits his range as a tackler. Lacks twitch and eliminating his surface area working up the arc is a challenge.
Processing - I wouldn't call him a slow processor but his reactionary skills must get quicker. Takes too long to deploy his plan of attack to beat blocks and winds up playing more reactively. Played in a number of spots for TCU, lining up inside and outside from a standup role and defending multiple gaps.
Play Strength - Has some issues exchanging power with offensive tackles and will occasionally set a soft edge. Modest ability to fight pressure with pressure and will get turned out of gaps. Dominates tight ends in the run game and plays through chipping running backs. Speed to power conversion is below average.
Versatility - Projects as a base end in a 4-3 with little upside to function in space. Has interior pass rushing upside but lacks the mass and strength to play there often. Experienced lining up in multiple techniques for TCU.
BEST TRAIT - Effort
WORST TRAIT - Burst and Flexibility
RED FLAGS - None
Collier carved out more playing time every season at TCU and peaked as a senior with 11.5 tackles for loss and six sacks. While Collier plays with an unrelenting motor, he lacks the burst, flexibility and nuance to become an impact edge rusher in the NFL. Despite a bulky frame and playing with good extension, he's a modest run defender which further limits his value. With that said, Collier projects as more of a rotational defender and his best course to playing time is likely to become a subpackage pass rusher from the interior.
