Basketball - is there a way to reduce its attractiveness?

Pool covers would be a really nice addition to the game. I know the Toddlers never, so far, wander over to a pool, but the fear remains, even so. In RL there are the motor-driven covers that allows for an easy on, easy off covering. I think you may even be able to walk on those, but I could be mistaken. I haven't had a pool in almost fifteen years.
