PROS: A natural block shedder, Gallimore is a force on the interior defensive line. He uses active hand swipes, a violent swim, and a push pull to dismiss offensive lineman and get after the quarterback. His compact frame allows him to play with excellent leverage, consistently getting underneath offensive lineman's pads. Thick, strong base and rarely ever driven back on base blocks. Now a three-year starter, Gallimore has the necessary experience and versatility to play anywhere from the 0 to 3 technique.
As effective as they come against double teams, able to split and move well laterally down the line of scrimmage. Gallimore is a nightmare to reach, as his leverage and hands prevents offensive lineman from getting their head across his body. Does an excellent job of keeping his eyes up, and will shoots open windows and follow pullers to the ball carrier. Relentless worker who works to pursue towards the football. Plays the position with necessary violence and will consistently keep offensive lineman from getting into his pads. Consistent tackler who can swallow up smaller ball carriers in his wide frame.
CONS: Gallimore does not have elite burst or get off from the interior, and will only project as an average athlete at the position for the NFL. He will rarely take every rep on a long drive and is subbed for often, potentially but not definitively speaking to his conditioning. While he is an effective disruptor against double teams, he can get too locked on beating them and get his pads turned. The play can occasionally pass by Gallimore as he processes the backfield before shedding blocks.
Against the pass, he can be an interior disruptor but will too often not take the most optimal path towards to quarterback. He has yet to have elite production as a pass rusher at the college level, and will occasionally be pulled off the field on strictly passing downs.
