that multiple fouls were a good idea?
I can't even imagine a coach bringing that up and other coaches agreeing to it. Especially if they considered how this would effect their team when it was called on them.
I think if this was made a point of emphasis and we called it for 1 regular season, the rule would be eliminated.
Or we would start hearing complaints from coaches, like "Look I know you called that foul, but his teammate also fouled him. That's a multiple foul by rule and we should be shooting 6 free throws cause it was a 3 point shot"
To which we'd have to explain how many free throws a multiple foul gives, plus explaining why we didn't have one on this play.
