Allen is built like a bowling ball. He has a low center of gravity, which helps him make a difficult wrap for defenders at times. He's able to keep his legs churning and run through half-hearted tackling attempts. Allen is a patient back that allows his blockers to clear the road before he charges down it. Allen's burst and raw speed are below-average. He's at his best when getting downhill immediately and getting a head of steam built up. His lateral agility is lacking at times, so asking him to operate in a stretch zone-based scheme wouldn't be ideal. With his limited athletic profile, Allen is a capped passing game option, but he can still operate as a valuable checkdown option. His route deployment will be limited, but he has soft hands with only one drop in his final season. His stature helps him in pass protection with a solid anchor. He can hold his own with incoming rushers bearing down, but speed rushers can give him issues. With his limited lateral agility, speed options can easily bypass him as they barrel toward the quarterback. Allen isn't a make-you-miss type of back, but he can deploy a well-timed jump cut at times to get the job done. He'll be heavily dependent upon his offensive line at the next level because he won't be creating a ton of yards on his own (especially near the line of scrimmage).
