This is actually a pretty normal basketball drill, but it also looks cool in GIF form. It's likely you've seen some form of this drill before -- with a coach leading, players practice their defensive slides and then dive onto the floor after the ball. But when the whole team -- in this case, the California Golden Bears -- is doing it, and they're doing it before an NCAA Tournament game, there's something pretty neat about it all.
It also kind of looks like a flash mob.
Hey, you in the back. Get on the floor! Get after that basketball!
Now set this to music and we're all good. The extra camera shake even adds to the whole scene.
