Allen left Penn State as its all-time leader in carries (769) and rushing yards (4,180), and his senior tape was the loudest of his career: 210 carries, 1,303 yards at 6.2 per carry, 15 touchdowns. The trait that travels is contact balance. He forced a missed tackle on a quarter of his attempts behind heavy boxes and rarely went down on first contact. The limitation that defines his projection sits right next to it. His passing-down PPA cratered to 0.074 against a 0.225 standard-down mark, the worst money-down number among the class's top backs, and he caught just 18 passes at 3.8 yards a grab. He runs between the tackles and finishes at the goal line. He does not catch and he does not protect.

Washington spent a Day 3 pick on him and then buried him on the depth chart. Jacory Croskey-Merritt already owns the early-down and goal-line role that overlaps Allen's profile most directly, Rachaad White was signed for passing downs, and Jerome Ford sits ahead as a receiving-capable third option. The one fit working in Allen's favor is scheme. New coordinator David Blough is installing an under-center run game built on counter, power, trap, and wide zone with fullback insertions, the downhill gap-and-zone menu that rewards Allen's vision and finishing behind Laremy Tunsil's line. But the same offense leans on backs who release into routes off play-action, which is exactly the work that keeps Allen off the field on third down.
