PROS: Built like a brickhouse and plays like one, too. Has enough power in one club to relocate an NFL-sized offensive lineman. Thick frame stays balanced well; he's able to bury or at least knock over a high number of opponents. Uses hump move effectively as a pass rusher, especially when slanting from even technique, to generate rush angles/push the pocket. Can eat up double teams with combination of power and mass; play style, frame, and traits all indicate ideal fit as a 0-tech space eater. Comes off the the line with good pad level generally, but can be a bit upright at times. Can flash decent quickness when slanting.
CONS: Athletic ability greatly in question and pass-rush upside is non-existent. No moves beyond hump move are present; hump move only featured so heavily because Gaines lacks the burst, quickness, or bend to attack any pre-existing gaps, even when aligned as a 3 or 1 tech. Lack of bull rush notably egregious. Despite good hand fits, shockingly unable to disengage from blockers when two-gapping, often closing down on the hole but failing to get involved with the tackle. Not a playmaker. Has poor situational awareness and regularly gets turned around, exposing back as a pass rusher; guess/jumps into the wrong gap against zone flow and traps/pulls. Not a high-motor pursuit player.
