I think one of the most important things we can do as coaches is to review our drills quite often. Not just find new drills, but to actually look at the drills we run and ask; Is this drill capable of giving more to the players than it already is?
A few months ago I asked that of the Walberg DDM Attack Layup drill of the Daily 45. The drill is great for teaching attacking layups and different moves, it focuses the act of training layups, and it only takes a few minutes each training session.
