McDuffie plays with a palpable energy and rarely gears down until the whistle blows. He's undersized, but is at his best playing inside. That's where his recognition talent and instincts take over and allow him to race to run lanes ahead of the block. He pursues with leverage but has the burst to accelerate and attack when it's time to finish. His full-tilt playing style will lead to occasional issues with pursuit angles and being out of balance as a tackler, though. He's feisty but takes time to free himself from blockers and was ineffective when asked to drop into coverage. He has the ability to become a quality backup with core special teams value.
