Despite the vaunted Jets defense last year, there were only 4 games the entire year where Zach was pressured at a lower rate than the opposing QB. Those games? KC and Mahomes; Denver and Russell Wilson; NYG and Tyrod Taylor; and Las Vegas and O'Connell. Las Vegas was legitimately a bad game by Zach, but as for the rest of the season, it's hard to become comfortable in the pocket and trust your line when you're constantly running for your life.
IOW, in all but 4 of Zach's games, Zach was the QB with the highest pressure percentage. That's not helping your QB win.
