This drill is just an extension of the Rim Finishes Drill I posted earlier today. This is a great series of moves that every player should add to their arsenal to work on to perfect. The ability to change direction and finish around the rim are key elements for players who want to play basketball at a high level.
When I performed this drill I had each player make each finish 3 times before moving onto the next move. You can adjust this accordingly as you see fit.
