Re: Improving offhand ball skills
Repitition and time.
Muscle memory is like building muscle: after you get the practice, your body takes time to build that muscle memory.
So ignore how stupid you look and just keep practing finishing with the left in every way possible. Do it enough and your body will adjust. One day you'll start to do lefty moves and you'll be like "whoa this is way more natural all of the sudden."
