Throwing a pot on the wheel of a car just shows that anything is possible. Well ... maybe. Anyone ever try to throw with the wheel upside down? LOL
Yes, the rotator cuff repair has altered things a bit. The range of motion & strength are coming back. What complicates matters more is the fact that I broke the wrist on that same arm about 15 years ago. It's healed fine and is strong but isn't at the "correct" angle. It's off a bit (i.e., can't throw a ball straight). But, I managed to adjust and made some decent things on the wheel. Then the rotator cuff ... aarrgghhh!!
Guess it's like you all say ... practice, practice, practice. And, I'll add ... patience, patience, patience.
