Out of bounds?

[gazebra]

The sub was from the defensive team and tripped the kid as he was coming off the bench due to the lack of space between the side line and the floor, and the official just simply gave the ball back to the offensive team as though it was out of bounds off the defensive team. In that case, I think it was the right thing to do, as it was clearly not an unsporting act. The defensive sub didn't even know the ball was right there, and he was trying to get past his coach. As for if the sub reached out, that would be the judgement of the official if he were protecting himself/the dribbler or not. If so, put it out of bounds. Neither coach said a word in the college game.
