How much is O.J. Mayo worth to the Mavericks? Probably not enough to get into a bidding war with the Minnesota Timberwolves and other teams who will pursue Mayo during the free agency period. Mayo was the Mavs' best player before the All-Star break last season, looking like a bargain after signing a one-year, $4 million deal with a player option for next season that he declined to exercise. His 2012-13 numbers (15.3 points, 4.4 assists, 3.5 rebounds, .449 FG, .407 3s) look pretty good as a whole. But Mayo faded badly in the final quarter of the season, and his defensive issues, inconsistent intensity and mental lapses were sources of great frustration to the Mavs' coaching staff and front office.
