Kentucky layups conditions and encourages competition. We run this drill every practice. We run two sets of 'two-minute' evolutions. I read somewhere that excellent women's college teams can get 60-70 layups in the two minutes. Last night we got 37 and 44. I'm optimistic that we can get to 50.
The drill quickly informs athleticism and speed, finishing ability, but most important, EFFORT. Some players 'bust it' on each opportunity while others need more 'encouragement'. Ideally, by high school players learn to get to the basket in two dribbles. In middle school, I encourage a maximum of three.
