At the end of the basketball game, Todd Schellinger is fouled with no time on the clock. Since there is no time on the clock, the other team cannot get possession of the ball off of a missed shot. Therefore the foul shots should be shot without any players under the hoop, similar to a technical or flagrant foul shot. When Schellinger is shooting there are rebounders under the basket.
