preventing the opponent from saving the ball?

[hoopguy]

Girls AAU game yesterday. Pretty standard situation basically what the op is about. Shot goes up and is an air ball, a1 boxing b1 as ball bounces inbounds and is heading out of bounds. b1 tries to go around a1 and a1 stays with box out. ref calls holding foul on a1 doing the box out. a1's coach goes ballistic gets 1 T then keeps up his yelling and gets T number 2 and gets tossed. Fans are now all mad and giving the ref hard time. Ref explains to fans that player a1 had arms behind and was holding. Fans and coach(before he was tossed) who do not know rules say 'that's how we coach them to box out!!'.

Long story but my point is.... Ref probably made correct call. Definitely made correct decisions after whistle with T's. But... If he does not blow whistle nobody on either team will be upset. This play happens all the time and is normally not called. Probably a lot easier to let it go and move on with the game. But of course that is why we get paid the big buck$!!!
