Hennessy has great hand placement and is able to use patience to get into the right position before holding his block. He has solid lateral quickness which enables him to move while blocking and sustain his block for as long as possible. Hennessy has some correctable problems like his timing in blocks against linebackers but those aren't a major concern. He has some athleticism but lacks the length typically needed to be a successful center in the NFL. Overall, Hennessy has good technique and athleticism which gives him a chance to become a starter but his poor physical traits like his lack of length will cause problems.
