6 Dallas Mavericks who definitely won't be back next season

1. Derrick Jones Jr.

Along with Markieff Morris, Derrick Jones Jr. is the only free agent on the Dallas Mavericks roster. Last summer, Dallas ended up signing Jones Jr. to a minimum one-year contract, and that was the best decision they could have made.

Jones Jr. quickly became the starting wing over Josh Green, and his production on both ends of the floor was excellent all season long. This season for Dallas, Jones Jr. averaged 8.6 points, 3.3 rebounds, 1.0 assists, 0.7 steals, and 0.7 blocks per game while shooting 48.3 percent from the field and 34.3 percent from downtown.

Jones Jr.'s defense was phenomenal and he quickly became a key part of the rotation, but his performance this season may have priced him out from the Mavericks re-signing him.

It was reported that Jones Jr. wants to return to Dallas during the offseason, but just like any free agent, he is expected to test the open market. Due to his excellent play during the playoffs, and selfless attitude, he may just earn himself a big contract.

The Mavs want to re-sign Jones Jr. too, and only time will tell just how high his value is on the open market. He proved that he is going to be an elite role player in the NBA for a long time, and if Jones Jr. wants a big deal, he may just go elsewhere.

This isn't to say that the Mavs are completely out of the race, but it's more saying that Jones Jr. has played his way to some big money this summer. Both sides want a reunion, but the Mavs will be limited when it comes to how much they can pay to retain him.

For all the latest on the Dallas Mavericks all offseason long, stay tuned.
