5. Loser: Derrick Jones Jr.

For the first half of this season, Derrick Jones Jr. was the Dallas Mavericks' best perimeter defender. Dallas signed him to a veteran's minimum contract over the summer, and he quickly outplayed that contract. His shooting was also looking phenomenal, and Dallas looked like they had struck gold with this signing.

Jones Jr. should still be considered a great signing by Dallas, but his shooting numbers have come back down to earth, and he isn't playing as well as he once was. Dallas also happened to make a move for another defensive stopper in P.J. Washington, making Jones Jr. a loser from this deadline.

He lost his starting spot, and his minutes and production have gone way down since the trade. Jones Jr. will likely still remain a crucial piece off the bench, but he won't be relied upon as he once was.

This season for Dallas, Jones Jr. is averaging 9.6 points, 3.7 rebounds, 1.0 assists, 0.8 steals, and 0.7 blocks per game. He has been the perfect role player for Dallas, and now his role will look a little different now that Washington has become Dallas' best defender.

It will be interesting to see how Jones Jr. performs after the All-Star break and to see if his 3-point shooting numbers can return to what they once were.
