I've said it before, I'll say it again, it's because Garrett has no idea how to manage a game and has no feel for game flow . No gameplan. No adjustments. No attempt to put people in position to utilize their strengths. It's just straight up here's the playbook, everybody go beat your guy. Good luck.
In his head if they lose or struggle, it wasn't the gameplan at fault, players just didn't do their job. This applies to backups to injured players and subs that come in. I mean, our dline does WHOLESALE changes on the fly, no matter the situation. So at some point, it could be 3rd and 7 in our redzone, and you'll see Tank, Collins & Quinn running off. Because Hyder, Hill & Armstrong are expected to 'do their job' like the starters. Which is why we never change our gamplan, adapt or do normal NFL level coaching things.
We've known this since the 2012 season. So much talent has been wasted since. Everything is a process to get better, except him. His Princeton mind knows it all because he picked the brains of Jimmy Johnson and Nick Saban for a day or two.
