Alan Stein shares non-dominant hand drills. The difference between an ordinary player and an extraordinary one is her willingness to go beyond, to "do more to become more."
Attacking the basket is where the rubber meets the road. Core offensive basketball skills include cutting, pivoting, dribbling, rebounding, passing, and shooting.
These drills work your pivoting (on the back or reverse pivot, your back leads), dribbling, and finishing (shooting) at the rim. At our level, I limit the "tricky dribbling" and work on crossovers, hesitations, combinations, and some back dribbling into crossovers (avoiding traps).
When we're playing well (and we're improving), everyone sees more cutting and passing and less dribbling.
