Mayo, 24, spent the first four seasons of his career with the Memphis Grizzlies, averaging 15.2 points a game. He is set to join a radically revamped Mavs roster that has added center Chris Kaman, forward Elton Brand, shooting guard Dahntay Jones and point guard Darren Collison in the last five days.
The third overall pick in the 2008 draft broke the news on his Twitter account, saying, “I will be signing with dallas! #Mavsnation.”
Not long after, Mavs owner Mark Cuban tweeted: “Welcome to the family OJ. We are fired up !! MFFL Mavs/Mayo Fan For Life !”
The 6-foot-4 Mayo came off the bench for the Grizzlies in each of the last two seasons and his scoring average dipped about five points below his first two seasons in the league.
He averaged 12.6 points last season, shooting 40.8 percent from the floor and 36.4 percent from 3-point range. Mayo could become the Mavs’ starting shooting guard alongside Collision, Dallas’ new acquisition in a sign-and-trade with the Indiana Pacers.
The terms of Mayo’s deal were not known. The Mavs had about $4 million in cap space remaining, which is what they could pay Mayo unless the move was part of a larger sign-and-trade deal.
Dallas has been careful to acquire players in the final year of their contract — Collison, Jones and Brand — or in the case of the only other free agent they’ve signed in Kaman, limit the deal to one year.
