Coaches control the game by how well he or she teaches the game. Coaches make the decisions from the sidelines by calling plays whether the game is in progress or by the way of timeouts & halftime. Coaches control who plays, how long they play, & who don't play. Coaches control who's on the team & who's not, & if you seen guards controlling plays on the court, then you've seen a coach doing his or her job of teaching their players to make decisios.
Skills is a word that I'm glad you threw into the mix. Curiosity asks, who gets hired & paid to teach the skills essential to play the game? Who's job is it to hone the skills the players learn; to shoot, pass, dribble, & rebound better, manuver themselves better with or without the ball & make good decisions?
And as far as dedication goes, coaches should dedicate themselves to teach better, inspire, & motivate. And if they can't, they should step aside & let someone else have the job.
