Some very smart people are not great at making immediate, on-the-spot decisions. Game day coaches must make immediate, on-the-spot decisions. Just because Garrett is very smart does not mean that he'll make a great game day coach.
I hope he improves, because if he doesn't, he won't be good enough.
I like many aspects of Garrett, such as his influence on player acquisition (especially the draft). Garrett has engineered a better than average passing offense. Garrett has won over Jerry and seems to have been a positive influence on Jerry (Jerry's decision making seems less reckless and impulsive than before).
FFS ZeroClub, it's a process.
Tom Landry was like, 18-46 in 196X and Jerry Jones gave him a 10 year extension and BOOM CHAMPIONSHIPS.
Systems need to be put in place. Way I was raised.
