I've wondered the same thing.
Greenie was a true superstar player, I wonder if he didn't have a huge bag of tricks to teach the boys. KG was super strong and quick, espec with his hands. Maybe he'd show 'em but didn't know how to train them to be violent with the hands.
Ring the bells that still can ring
Forget your perfect offering
There is a crack, a crack in everything
