Unfortunately I did not see this game, only the replay of the last minute played, so I am unable to comment on game consistency.
My first thought when I saw this was, the defender got killed. Watched it again and started thinking about advantage/disadvantage. The defense was not put at any real disadvantage on the play, other than finding himself in amongst the cheerleaders (disadvantage for an 18-22 yr old
I think not). There was no play on the ball at this location and it looked and sounded like a flop. Now had the offense attempted a shot, I think the result would have been different.
A couple of things I also considered on the play. The defense was almost under the basket at the time of the collision and the offense didn't have the ball and sort of attempted to slow up. 99% of the time this is a no-call at the D1 level. He was essentially guarding a spot under the basket. The other thing I noticed is that the defender left his player (the shooter) wide open instead of defending against the 3 pt play which is the last thing that should've happened. I think most coaches would be saying to their players, "don't let them take a 3."
