After coming from the Magic, Shaquille "Superman" O'Neal became a dominating force in the fallen Lakers dynasty, winning three NBA championships, three Finals MVPs, and one season MVP during his eight seasons there.
Dwight "Superman" Howard, who also came from the Magic, struggled partially because of his back injury while the Lakers barely made it into the playoffs. He ended his days as a Laker by getting swept in the first round by the Spurs. It's clear who was the better Superman in LA, but that doesn't mean O'Neal won't still send a shot toward Howard's way.
According to O'Neal, Howard left for Houston because he couldn't handle the pressure:
It was expected. We've all been in LA, and not a whole lot of people can handle being under the bright lights. Everybody wants to do it, but when you get there, there are certain pressures. I think it was a safe move for him to go to a little town like Houston. That's right, little town. I said it.
Also, Houston is actually the fourth-largest city in the country, so it's not really a "little town."
