I think the reason Dorseys offense looked ok overall was because Josh would go berserker mode and try to save the game, hitting long runs and big plays which would ultimately elevate the stats. I dont know how to track this but I would love to see DVOA and EPA/play for plays made "in structure" between Dorsey and Brady. Under Dorsey it felt like nothing happened in structure. The entire offense was drop back, scan, scramble, hit something out of structure. It felt impossibly difficult. Under Brady it felt like Josh hit a lot more in structure. So while the final result of a drive may be the same, it just was exhausting to watch under Dorsey.
