The left hand is the key to the game. It takes a delicate touch of the left hand to catch and pass. Left handers may have a disadvantage, but not for the reason that everyone is talking about. The real disadvantage is that left-handers are used to doing their crusher strong work, the kind with huge motions and full force, with their left hands.
The normal course of kinetic learning in the cerabellum is for the weak hand (left in right handers) to learn from the strong hand (right in right-handers). The weak hand follows the strong hand, helps it out, and learns to do what it is doing without really doing it, much like a son learns from his father by being present and watching. Then when the son grows up, he often does better than his father, because he learned all the techniques without performing the mistakes.
In like fashion, the left hand in a right-hander is usually, at the start, less competent, but is able to become more competent than the right hand, because the right-hand does not usually want to learn from the left hand.
I could say much more, but to cut to the chase, a left-hander needs to learn to use a delicate touch, and much finesse with his left hand. The left hand is key, because it controls the five-rod, which is the key to the game.
Notice, that most left-handers can shoot hard with their left hand, but do not bother passing much. This points out that they don't trust their right hand to do the hardcore shooting up front.
But all this can be overcome by good coaching and proper practice.
