It is great coaching. If they don’t call it, then it’s not a foul. It’s the same in every sport. If the ump gives pitchers the outside corner, he’d be crazy not to take it. If he’s not giving it, then the pitcher has to adjust to that ump’s strike zone. Basketball is the same way. Players have to adjust to what the refs are allowing or not allowing on any given day. And coaches are supposed to help their players make those in-game adjustments. Complaining that the refs Don’t know what they’re doing is unproductive and is a waste of time. It would be like a football coach complaining about bad weather. Just play the game.
