Defensive lineman who isn't a pure one-gapper or two-gapper, but has enough play strength and athleticism to operate in either capacity. Butler plays more stoutly than his top-heavy frame might indicate. His blend of body control and grit allow him to reverse course against block sustain and get back into the play. He's not overly explosive up the field but has enough edge rush and secondary effort to become a nuisance from time to time. Butler should step into a rotational role early in his career before competing for a spot as a starting three-technique for a 4-3 unit.
