Zone-scheme center with below-average play strength but a good feel for getting to his blocks on the move. Hartwig can improve his engagement power with better hand work but will never be the guy to neutralize or move bodies in front of him. He can get to his landmarks laterally and is patient and accurate when working up to linebackers. Hartwig is average in pass protection and will need to prove he can hold up against bull-rushers. He’s a pesky run blocker when he’s on the move but his limitations narrow his list of potential landing spots.
