It all depends on who you work for. But I will say there's way more grind for no reason coaches than not. They rather over work and over prepare cuz they think they'll be outworked, not because there is so much work to be done. Also you got coaches who wanna look like they're doing a good job just because of the amount of work they put in so if/when something goes wrong, they won't get ripped because they were out the office or with family. Thats a 100% Saban environment though, I know coaches who have multiple phones and copies of keys and they'll leave them on the desk and dip to make it seem like they're in the office or they'll be on the phone with their boys all day shooting the $%#* but tryna look like they're recruiting, its all opticals. Been in P5/FBS for about 10 years now and it all starts with the personality of the head coach and everybody else will do what they think he wants so they're not on the chopping block.
Now with recruiting they'll over do it and put it all on recruiting staffs just so they can volume shoot. Won't turn kids down that wanna come on unofficials, get as many kids to camp as they can, watch film on all these transfer portal kids knowing they're not taking but a couple, its ridiculous.
