Or I could say that the officials made an agreement (or were briefed by their superiors) to allow more physicality and the fact that it benefited one team more never crossed their minds.
UConn has played and won many physical games and Arizona played well that night and deserved to win. UConn's injured pg was a bigger factor than the refs. But that doesn't change how the game was officiated. And the play was used because there can be no doubt that it was seen and ignored. Most bad calls fall in a grey area. This was a no-doubter.
On the play in question Bueckers was halfway between the basket and foul line and in the center of the paint. There were couple of players down low but no one within 5 feet of her when she established position in front of the Ariz player. The player ran right at Bueckers who was standing still and using both arms like she was throwing a chest pass she shoved Bueckers back about 6 feet, knocking her on her ass and then, unguarded, took a pass and scored a layup. Again, there was no one else near either player and it happened in the middle of the paint. To suggest that 3 refs didn't see it is ridiculous. It's obvious that the officials had intentionally ignored it. The only question is why and there seems to be a difference of opinion on that.
getting back to the topic
Bueckers needs no bodyguard. UConn doesn't back down. I remember watching Kelly Caine body slam a small player in a rebound battle and then stand over her screaming at her. Pat was incensed that T was called. Tenn made physical intimidation part of their identity. Not dirty play, but plenty of hips and swinging arms. When I want to be sarcastic I call that style "chuck & scrum". Try to feed the big players inside and if that doesn't work then someone tries to hit the rim with a shot so the bigs can scrum for it until it goes in. Good examples are SCar's final shots in regulation against UConn and Stanford last year.
