I would be less bothered if it looked like he was cussing up a storm trying to motivate players that’s just frustrated coaching trying. His cussing just looks like a tantrum that’s the bad look.
There is a whole lot of cussing and f-bombs on the sideline at college games and also more high school games than you think. I guess these coaches don’t know people in the stands can hear it but we can!
Also middle school coaches are sometimes the worst at it. I think my middle school coaches screamed and cursed to act tough. When I got to higher levels the coaches were more relaxed and only cursed when we were being silly
