Two injuries robbed Allan of valuable game experience and dulled some of his development. He's a physical specimen with the strength to hold his own at the point and rid himself of single blocks with twitch and technique. However, he often seems lost in terms of play recognition and what he needs to do to get in on a play. He has some upfield rush charge but isn't a natural bend-and-trim rusher, so building out a more thoughtful, diversified attack is a must. Allen has the traits to play edge in odd or even fronts but additional development is critical if he wants to become more than just a quality rotational defender.
