Interesting video. There are some glaring fundamental mistakes in Pickett's reads, but nothing that shouldn't be fixable with a little more experience. Also, it gives a different perspective for me on Canada's offense -- a lot of open receivers are eventually running free on these plays, and not being located by the quarterback. Hard to say exactly who's to blame on any particular play, but maybe Canada isn't as bad as we thought.
I would, however, take the KP's poor numbers against zone with a grain of salt. Advanced metrics at playerprofiler.com had Mac Jones #1 in the NFL in 2021 against zone coverage. Last year, he was 31st. Most NFL defensive coordinators make the necessary adjustments; the Steelers and Pickett will have to do the same to get better this season.
