You're missing the point. It wasn't controversial and you don't want to make it controversial by having the officials signal two separate things. That's an example of good officiating.I don't care where the hell it was on the court that was awful. It wasn't like it was really controversial or anything. My dad an Iowa fan agreed it was awful.
Edit: I'd give it a pass if it was a normal signal but it was obviously playing to the crowd with how it was signaled.
And referees aren't robots...they feel emotion during the game. I'm sure you don't mind when we get fouled, the shot goes down and there's a more emphatic signal to count the basket.
Its unfathomable to me that someone would cry about how an infraction is signaled.
