A2 is standing at the FT line in BC and A1 inbounds the ball by rolling it on the floor to save time (so the clock won't start). But, the ball touches OOB by a good foot or so on the "bowling ball style" inbounds pass. Big deal?

This exact play - a throw-in violation to conserve time - caused a lot of discussion locally about 5-6 years ago during a high school final!

The calling official on the game called the violation. I would have too.
