What does your human player do in the game, does he attempt to throw tubes from endzone to the rack, manual load, or just stand there and look pretty? We have debated the benefits of each of these, options and have come up with a humanplayer (me) that can do a mixture of all three. I posted a video of him making the throw.

(by the way the two innertubes on the floor were not thrown by me, just to clarify)
