This happened in a March madness game and caused a lot of confusion by the announcers. I think their rules official came back and said the call on the court was correct, but did not give much explanation.
Team A is inbounding the ball under their own basket. Throws the inbound out toward half court. Pass is too high and Player on team A tips the ball but can’t catch it. The ball goes into the backcourt. Team A goes and gets the ball in the backcourt. Should this be a backcourt violation? Or not because possession was never established in the front court?
