You are correct. The talent is there but without the coaching behind them they are fighting a lost cause. As far as ability goes, he does not play the correct 5. His scorers (the twins) are always on the floor no matter the turnovers or bad play and his front people make many turnovers and show no concern they are playing badly. The post play could improve with the correct combination of Taylor and Craig together. THey play very well together offensively and certainly defensively. There needs to be team leadership and I only see one person accepting that role on a regular basis. The twins are leaders offensively and Taylor is a big leader all the time especially defensively.
IN short, the coach needs to play the players that care and show determination in the game. I know he is young but he has had time to figure out the talent needed on the floor.
