The 2017 off-season saw the departure of Dean Demopoulos and the hiring of Dean Vickerman as head coach. Under Demopoulos, United underachieved due to a one-dimensional game plan and a lack of direction at the defensive end. With Vickerman came a cultural shift based around sharing the wealth offensively and leading from within. With a returning cast of Goulding, Ware, Boone, Wesley, Andersen, Barlow and Majok, United acquired the services of Casey Prather, a swingman coming off back-to-back championships with the Perth Wildcats. United also signed former one-time Melbourne Tiger Daniel Dillon, but an Achilles injury to Dillon forced the team to sign Peter Hooley in his place. United were title favourites at the start of the 2017–18 season, but fell to a 2–3 record following a loss to the Brisbane Bullets in Round 4. In December, Prather went down with a possible season-ending elbow injury and was replaced by Carrick Felix. With defensive-minded Felix in the line-up, United went 9–1. Felix was removed from Melbourne's active roster in mid-February following Prather's return from injury. United finished the regular season as minor premiers for the second time in three years, earning a 20–8 record. They went on to sweep the Breakers in the semi-finals to reach the 2018 NBL Grand Final series. There they faced the Adelaide 36ers. With the series tied at 2–2 heading into the deciding Game 5, Ware and Goulding each scored 23 points with Prather adding 19 points, 11 rebounds and five steals to lead United to a 100–82 win, as the franchise claimed their first NBL Championship under the new moniker.
