When O.J. Mayo was in Memphis for four seasons, he settled into a place that was not near the touristy hustle and bustle of Beale Street. "I was about 25 minutes out [from the arena]," he said recently. That made it tough to have spur-of-the-moment shooting sessions in the evening, when structured team workouts were over and players were left to their own devices. After joining the Mavericks, Mayo moved into a place five minutes from American Airlines Center. "Now it's like going to shoot in my backyard," he said. That's one of the main differences — but certainly not the only one — in Mayo's life since leaving Memphis. He will play his first game as a visitor at FedEx Forum on Friday night when the Mavericks meet the Grizzlies for the first time this season. Mayo has taken the high road since leaving Memphis in free agency. He was signed by the Mavericks for one year, plus a player option. As the eighth-leading scorer in the league at 20.6 points per game, there's no way Mayo will exercise that option. He'll have an opportunity to make a lot more than the $4.2 million he would get with the option. The thinking in Memphis is that the Grizzlies are better without Mayo. That may be true, but the Mavericks know they are better with him. He's become an efficient scorer who is also a solid rebound and assist guy. "He's worked to become one," coach Rick Carlisle said of Mayo development into a proficient offensive player. "That's the key thing, you know, to put the work in, study the game, study his game and work at it. He's done a lot of good things."
