Both make excellent decisions. Both take very good care of the football.
Zach Wilson had better downfield accuracy, and it shows in stats. 12.6 yards per attempt versus 9.0 yards per attempt. Zach did it across an entire season too, we haven't seen it yet from Jaren for a whole season.
Jaren is doing it against tougher teams, so there is that, though.
Seriously, my memory of 2020 Zach Wilson was him chucking it 30+ yards down the field constantly, accurately, and completing almost all of them.
