O.J. Mayo has a ritual whenever he visits an NBA arena. He does it everytime. "Whenever I walk into a building before a game, I look up at the rafters," Mayo said. "I look for the banners." Mayo sees one in Dallas. He wants to add another. Mayo is known for many things. Not all of them are positive. He's been known has a shot-hunter, a coddled high school star who hasn't matched his immense talent with the proper work ethic. That Mayo was nowhere to be found Tuesday night. All of his thoughts were about winning. "I respect the work ethic, first in the front office, the coaching staff and Dirk," he said about picking Dallas this off-season. "I think its a great opportunity to come here and continue the winning."
