I guess Channing Tatum isn't much of a hoops player
The film featured loads of game highlights but I don't think they ever showed him doing anything except diving for a loose ball, or making a random pass or steal, he never did anything around the rim. By contrast, many of those other actors clearly had game in real life.
I was surprised that they didn't use the high school dance scene to showcase Channing's hip hop dance moves, what a wasted opportunity!
