You're clueless. Zappe was changing the plays at the line all the way back in college. His coaches gave him that freedom because he processed fast. Zappe can make all the throws. The coaches are seeing this and allowing him to pass more. He had 34 attempts today. Mac averaged 32 in his 3 games.
Nothing but excuses from the Doubters: wide open receivers, better OL, easy game plans, he's being handled, blah, blah, blah.
BTW, I see a lot of talk comparing Zappe to Mac's games this season. Here are Mac's stats from the 2021 Bye to this season:
Games: 8
W-L: 2-6
Attempts: 34 per game
Comp %: 62.5%
TD: 10
INT: 12
Sacks: 12
Thoise are not solid numbers for a starter. Mac has not been playing well going back to the end of last season.
