Very possible. The NCAA rulebook says nothing about contact with airballs in the traveling section. In the Double Dribble section, it says: It seems to differentiate between shots and passes that don't touch another player, which suggests that an airball can be retrieved by the shooter in NCAA ball.
So I'm just trying imagine how this worked; how did he manage to not send it out of bounds, but didn't hit the rim or backboard?
Say he throws the ball up and it looks like an air ball, then jumps and grabs it out of the air to dunk it. Like an alley opp to himself. Is that a travel?
It happens quite often. Say you are running at the hoop from one side and air all is short or even long and you just keep running and catch it.
Travel? That would be just fun to see. A good dunk in rat ball is always fun even when you're the one getting dunked on. It's all the guys who think they can dunk that are annoying.
