Really dumb play

[BEAREF]

I had a similar sitch last week. Home time had delay of game warning earlier in the 2nd half for crossing the line while defending the throw in. With 10 seconds left in the game and home team up by three visitors are inbounding the ball on the sidelines right in front of the home bench. The home defender not only reaches through the plane but also steps across...an easy T to call. The visitors make both free throws and then score on the inbounds play and win the game by 1. Talk about a dumb play
