Because the Mavs are not yet over the salary cap, they were able to sign Ledo for four seasons instead of the two years second-round picks on over-the-cap teams get. A sourced told Grantland.com's Zach Lowe that the deal, which starts at $60,000 above the rookie minimum, is nonguaranteed in each of the last two seasons.
The Mavs were under the cap because they have yet to make the contracts for center/forward Brandan Wright, guard Wayne Ellington and center Bernard James official. They are able to exceed the cap to sign those players because they own Wright's Early Bird rights, are using the "room" exception to sign Ellington and will sign James for the minimum.
The Mavs acquired Ledo by trading for the No. 43 overall pick, giving up Brooklyn’s 2014 second-round pick to get the 6-foot-7 shooting guard.
Ledo is a project with scoring potential who did not play college basketball. He was one of the top high school recruits in the country in 2012 and signed with Providence, but he was limited to practicing with the Friars after the NCAA ruled him ineligible.
