Imo ZDS is a mix between McPhee and Upshaw. He has McPhee's size but lacks the burst McPhee has in his first step. He makes up for that with strength, like Upshaw, but unlike Courtney (and even McPhee when he came into the league), ZDS already has a strong understanding of hand placement and leverage, has a variety of pass rush moves, and sinks his hips well to pivot off of blocks. Net, I think he could develop into an even better hybrid than McPhee, combining Upshaw's edge setting presence with McPhee's ability to move around the line for sacks.
