He doesn't look like he has James Worthy's potential.
Does he have the potential to be a non-HOF level, poor man's James Worthy?
Eh. He resembles Worthy in size and build, but that's about it. Worthy had incredible touch and was an excellent finisher around the basket. He was decisive with the ball. Green seems to like to feel out the defense, getting the ball and waiting a few seconds before making a move. Worthy was active and he was decisive - he'd get in position, get the ball and go straight into his move.
I also think Worthy was even more athletic. Quicker first step, certainly.
