Making Chimichangas

I have been through this in a sports setting. Did we get on guys for mistakes? Yes. Did we resent the coaches for it? Yes. Did it make us a better team that didn't make dumb mistakes and came together to play well? No. We made less mistakes sure, but we didn't like the coaches for it and never gelled as a team because guys were always on each other.
I've been on another team that used the frost approach. Make mistakes at full speed and don't punish the team. We played better together fought for our coaches a s teammates and had more success.
Why would you "resent" your coaches? Their job is to win football games. As a player, I would hope your goal would be to want to win as well--and that you'll be willing to pay the price to do what it takes in order to win.
The military is not much different. No matter how hard our drill instructors hammered us, no one ever resented them; because we all understood they had a job to do, and it was our job to learn the training that could potentially save our lives in combat.
Point is, in my opinion, hating or resenting your coaches/instructors for demanding excellence is pretty pathetic. If you're a player on a college football team and you're not there to give your all to win, then leave and go do something else. Don't be the anchor or dead weight dragging the yeam down.
