Yesterday evening, it was reported that the Dallas Mavericks have intentions to go after two particular free agents this summer. Those two guys are Kemba Walker of the Charlotte Hornets and Khris Middleton of the Milwaukee Bucks. Both players appeared in the All-Star game this year and are considered top level targets.
According to Marc Stein of The New York Times (subscription required), the Mavericks intend to be involved in the free agency discussions with both of these players. He sites league sources in this and follows it with the Mavs likely backup plan of pursuing other two-way wing players to help fill out the roster.
