if the two controversial calls get overturned with better camera angles. Let's say Hifo's ball falls incomplete instead of as an interception. Then BYU makes the 4th down conversion with a run play. Zach then isn't throwing into a team expecting pass at the end of the game. BYU wins and Zach has zero turnovers. The perception changes completely without changing his performance.
Zach also rushed for 2 TDs and should have a 3rd one. Just because the play calls for run doesn't mean that Zach wasn't a big part of that.
As I said earlier, people need to lighten up and realize Zach's potential to become BYU's next great QB. Learning in game is part of nearly every QB's journey as underclassmen.
