"I'm very excited to be here. I just want to fit in with a damn good team," O'Neal said at a news conference in Phoenix. "I'm just here to make everyone else better. I wanted it to happen because I was coming to a fabulous team. Helping them get to the next level will be exciting."
O'Neal has averaged 25.6 points a game over his 16-season NBA career but has managed a career-low 14.2 points in 32 games this season.
Phoenix leads the NBA Western Conference with a 34-15 record after two consecutive seasons of losing Western Conference finals series. O'Neal, with four NBA championships behind him, was traded to help get the Suns over that hump.
