The Dallas Mavericks believe they can tap O.J. Mayo's star potential. Dallas signed Mayo, the third overall pick in the 2008 draft, to a one-year, $4 million deal with a player option for a second season after he spent four often frustrating seasons with the Memphis Grizzlies. Mayo's best statistical season was his rookie year, when he averaged 18.5 points, 3.8 rebounds and 3.2 assists. He posted similar but slightly lower numbers the next season, and his statistics declined significantly while serving as the Grizzlies' sixth man the last two years. The Mavs switched gears to Mayo after plans to lure Deron Williams to Dallas fell apart. "We went on the option for the big free agent. That didn't work out. Honestly, that wasn't my first choice," owner Mark Cuban said Monday. "Sometimes the best deals are the ones you don't do and they lead to better things. And I think that's what happened now."
