Not sure about the cape, that was something he did long before the Lakers.
It was good to see the effort last night. Especially the part about trying to make the pick and roll work with Nash. I never understood his previous lack of effort here as it was a vital part of Orlando's offense and he was good at it. Maybe not Amar'e good, but decent enough and I never saw a good reason why he couldn't duplicate some of that success if he was working with one of the best ever pick and roll PG's.
But no, he was stuck thinking he wanted to be strictly a post guy. Well I hope he discovered that effective playing in the post takes a lot more effort than just showing up. MDA says "Ball Finds Energy" and that applies to post players as much as it does to anyone else. It takes work to get good position to receive a pass and be able to do something from there. Perhaps his back is preventing him from being as effective down there as he could be. But that could be a blessing, it's forcing him to show energy in order to get the ball thrown into him.
Ball finds energy: keep being energetic at both ends, defend the rim and do the pick and roll as well as the post ... and he'll get that jersey on the wall and the statue in front of Staples.
