I have spent alot of my life in a coaches office because my dad is a football coach here in Louisiana and I've been somewhat of his right hand man since my early years, so I think I can provide somewhat of an inside view of what coaches think of an incredible athlete who does stupid stuff...
We all go through those stupid years in which we act stupid, do stupid stuff, and are immature, but we all eventually mature out of it, some mature early in life, some mature when they are forced to when the error of there ways catches up to them. But everyone has that one moment when everything that has been preached to you over and over again to you by parents, coaches, and teachers clicks and you all of a sudden look back on your life with fresh eyes and see what an idiot you were.
These kids that you see doing stupid stuff and screwing up there athletic career are the ones that mature later and as a coach when you take a chance on these athletes you can preach and scream all you want at them, but it isn't gonna take until they have this moment and things come into perspective, and as a coach who takes a chance on these players, you are constantly waiting for them to have this enlightenment. Believe it or not, more time than not they grow up, before it all comes back to bite them in the butt and as a coach you feel proud of him.
But about 25% of the players who mature late never get this Epiphany and they are the ones you see in the news failing drug test, shooting people, killing dogs, raping women, getting in bar fights, resisting arrest, and the list goes on and on and just because this small percentage that doesn't get it these coaches get a bad rap and are ripped to sheds by you people.
Believe me I have seen more kids than I can count be the clown of the team, not work hard, not go to class, and still be ahead of the players that bust there butt to make a 3.0 and never miss practice. And then just all of a sudden it hits them, and you see them steadily start to work not only harder but extra, go to class and make good grades, and steadily fall in with a better crowd. And I have to say, whenever they do that, it's one of the best feelings as a coach you can have because you finally know that this guy get's it.
So don't blame the coaches for the minority of the guys that don't get it, just remember for every 1 player that coach took a chance on and got the short end of the sick, there are three more young men that he took a chance on that got it and because of that changed the players and a those around his life.
