Someone needs to invent a contraption like a tennis bowl launcher, except for basketballs. They need to make them so they throw the ball at variable speeds and arcs. The coaches should use three of them. Put big men like Gueye under the basket and start firing balls at them from every direction. A hundred balls a day until they can catch the damed things with some degree of reliability.
I'm thinking shock collar but the NCAA may get nasty!
