Miller is an active defender, a very active defender. He plays like his water bottle on the sideline is filled with trucker stop coffee. He is always moving and bouncing around and he is a tough kid to get and keep blocked. First off he has a nice build. He will need to keep adding weight, but he is a tall long limbed kid with plenty of room to keep bulking up. He is quick off the ball and very active with his hands. He is constantly using them to try and swim over, shed from, or push by blockers. He in general is a pretty quick twitched kid and can jump around blocks. Some of what is does is unorthodox and at times his hyper nature will get him out of position, but for the most part he makes it work for him. He can get penetration and does a good job of being able to follow blocks and jump in the hip pocket of pulling linemen. While he is an active kid he is also tough at the point of attack. It is not all just trying to avoid blockers as he can use that reach to press blockers off of him and hold his ground. He displays good natural strength and should continue to improve in this area as he gets into a college weight program. He needs to watch his pad level. He flashes the ability to play low, but his style will leave him tall and with his chest exposed and he can get caught up with blockers. He is a solid tackler though a bit sloppy at times because he can be wild. Good short-area change-of-direction skills and speed. He can cause problems rushing off the edge and if given the corner he can get up-field and in the quarterbacks face. He is once again active with his weapons, but needs have a plan at times. Miller is a good looking kid and a fine prospect. He needs to channel some that energy at times into better technique, but most of his flaws can be fixed. He is a good football player now and also impressively possesses nice upside.
