What a truly bizarre attempt to overcomplicate things.
Look, I know Collins is your boy. I know it hurts. But this time he messed up. The Magic spread the floor for Banchero and it was mano a mano from there. In that situation you do whatever it takes to stop a guy from getting a layup. You live with a 3, you live with a pull-up, you take a hard foul if necessary. But above all, you stay between your man and the basket. If you can't do that, you shouldn't be there. Banchero didn't even need a screener.
The Jazz were not going to gelp off any of the other players and that was the right choice. Sometimes it really is that simple – either you stay in front of your guy or don't. Collins is not a good defender and the Magic knew it. No need to scapegoat anyone else.
