Hailes is one big dude. He lacks ideal height on paper, but on film he looks like a massive kid with a bunch of bulk packed on his frame. For the most part he is a space eater that can plant himself in a gap and gobble up action that comes his way, but you can't be too fast to judge this big boy. He is not consistent, but flashes good quickness off the ball and will shock you how quickly he can get moving at times. When he can get to the shoulder of a blocker, he can plow his way into the backfield. He does a good job of being able to get into a gap and stay square. He moves well laterally between the tackles and can be a disruptive player. When he brings his hands, he can deliver a pop and knock a blocker on his heels. He tends to play high and can let blockers get into his chest, but he is still tough to move backwards. Tries to engulf ball-carriers around the neck, but overall a serviceable tackler. Hustles around, but this kid is built to do damage between the tackles. Can provide pressure as a pass-rusher. He can bull rush and collapse pocket. When he gets to half-a-man, he will try and work a move. He can be troublesome when he gets to the hip of the blocker. If he watches his weight, he can give you solid reps with some disruption and big plays peppered in.
