The Dallas Mavericks are reportedly planning to pursue Khris Middleton and Kemba Walker in free agency this summer, according to Marc Stein of the New York Times.

The Mavs will have cap space this offseason to sign a max contract player. Both Middleton and Walker will become unrestricted free agents on July 1.

But league sources say that the Mavericks intend to fling themselves into the chase for Khris Middleton and/or Kemba Walker with gusto in hopes that they have a shot at one of them. Wings with two-way ability figure to be another emphasis if Dallas is unsuccessful in pursuit of the big names.

Walker has spent his entire career with the Charlotte Hornets. The All-Star guard averaged 25.6 points, 4.4 rebounds and 5.9 assists per game in 2018-19 while shooting 43.4 percent from the field, 35.6 percent from beyond the arc and 84.4 percent from the free-throw line.

Middleton, meanwhile, has found a home with the Milwaukee Bucks after starting his career with the Detroit Pistons. The swingman put up 18.3 points, 6.0 rebounds and 4.3 assists this season. He is widely expected to re-sign with the Bucks, but it can't hurt for the Mavs to try and pry him away from Milwaukee.

The Mavs are building their team around Luka Doncic and Kristaps Porzingis. Getting a third high-caliber player will give Dallas a shot at making the playoffs in 2019-20.
