The attitude, lack luster effort, rebounding tenacity, all examples of coaching.
Also, you are 100% wrong on this.
These are perfect examples of the opposite actually. These are things a coach cannot control. He can try but these things are on the players. A coach can bench a player who is not bringing these things to the game, and I think Miles is trying everything he can before he ends somebody's playing time.
I know we like to think a coach is responsible for everything, but those things you listed can't possibly be on Miles. These are pretty much grown men you're talking about. Nobody controls your effort, attitude, or tenacity throughout your everyday life, nobody but you. Why would you expect a coach to control those things from five, six, or seven 19-22 year old kids? The effort is on those young men, Miles is clearly doing what he can to show them they need to step up. Hence, the topic of the thread.
