5. Signing Derrick Jones Jr.
The most recent move of the Mavericks offseason came on Wednesday afternoon as they signed Derrick Jones Jr. to a one-year contract.
Jones Jr. had been a rumored target for the Mavericks over the last few weeks, and Dallas decided to sign him.
The Mavericks needed some more wing depth, and Jones Jr. gives them an athletic wing that can come into the game and hustle and play defense. Jones Jr. is also an excellent dunker and is a good finisher in transition.
Despite being a great dunker and an underrated slasher, Jones Jr.'s role on this team will likely be to play lockdown defense. His long frame and athletic ability allow him to guard multiple positions, and block shots that most players aren't able to block. He has a 7-foot wingspan and contests everything.
Another intriguing part of his game is his improved three-point shooting.
Jones Jr. shouldn't be relied upon as a knockdown three-point shooter by any means, but he shot a career-high 33.8 percent from downtown last season. He's only 26 years old, and we could see him continue to improve in that area and become a trusted three-point shooter.
Dallas signing Jones Jr. could turn out to be a great move, as Dallas needed a player with his defensive ability to come off the bench.
