I had a crazy one Sat - B13U. A inbounding ball. B matching up man to man. I hand the ball to A1 to inbound and I guess B1 then discovers - "Hey, that's the guy I'm supposed to be covering!" So, B1 runs across the floor and jumps at A1 (who is holding the ball out of bounds) flailing his arms and all trying to prevent the inbounds pass .....and jumps right across the line out of bounds!
TWEET! Warning on B.
Never saw that before. Almost ran right into him. Sheesh.
