Oubre began the 2018-19 season with the Washington Wizards before being traded to the Phoenix Suns on Dec. 15. The Kansas product started a career-high 19 games on the year, 12 of which came after he joined the Suns. Oubre's scoring average (16.9 ppg) in Phoenix was a career-best for the 6-foot-7 small forward. He also saw 29.5 minutes per game with the Suns, a higher mark than he ever saw as a member of the Wizards. After some time to settle into his new surroundings, Oubre averaged 21.0 points and 5.9 rebounds in nine games in March. He scored a season-high 32 points versus the Pelicans on March 16. That was unfortunately his final outing of the year, however, as his season was cut short due to a thumb injury that ended up requiring minor surgery. That last outstanding effort marked one of 50 times Oubre reached double figures in 2018-19. Helping contribute to that was 108 made three-pointers in 2018-19, which now makes it back-to-back seasons with 100-plus made threes for Oubre. He shot 32.0 percent from beyond the arc -- the second-best mark of his four-year NBA career.

Buoyed by a significant increase in playing time (27.5 minutes per night), Oubre took the major step forward the Wizards had been hoping for during the 2017-18 season. The former No. 15 overall selection in the 2015 NBA Draft played in 81 of Washington's 82 contests, including each of their six playoff games. Offensively, Oubre set new career-highs across the board, as he posted career-high marks in points (11.8), rebounds (4.5) and assists (1.2) per game. One of the main reasons for Oubre's scoring production was his improved three-point shot -- he nailed 34.1 percent of his tries from deep after connecting on just 28.7 percent during the 2016-17 season. Oubre also shot a career-best 82.0 percent from the charity stripe. Defensively, he averaged 1.0 steal per contest. He swiped three or more steals on six different occasions, including a career-best five steals in a win over Portland on December 5.

Prior to his second NBA season, Oubre again showed signs of potential while leading the Wizards in scoring (19.2 ppg) and rebounding (5.6 rpg) through five summer league games. While Otto Porter beat him out for the starting small forward job, Oubre remained one of Washington's key contributors off the bench. He recorded his first career double-double Nov. 28 in a win over Sacramento, scoring 10 points and corralling 11 rebounds. Less than two weeks later, Oubre set a new career high with 19 points in a Dec. 10 victory over the Bucks. When it was all said and done, Oubre averaged 6.3 points and 3.3 rebounds across 20.3 minutes over 79 games (five starts). He was most productive over the final stretch of the season, averaging 11.4 points and 4.9 rebounds across 27.9 minutes in the last 10 games. He reached double figures eight times over that span. Oubre and the Wizards finished fourth in the Eastern Conference with a record of 49-33. They got past the Hawks in the first round with Oubre averaging 5.2 points over six games but were eliminated by the Celtics in seven games in Round 2. Oubre averaged 6.5 points in the series against Boston but didn't score in Game 6 or 7. He battled through a knee injury, which ultimately required PRP injections in the offseason.

After one season at Kansas, Oubre was selected 15th overall by the Washington Wizards in the 2015 NBA Draft. He logged six games for the Wizards in Summer League play and battled an ankle injury in the preseason, but he was ready for his NBA debut Oct. 30. While Oubre didn't record a stat in just one minute on the floor in that contest, he was more active in his next appearance Nov. 6. In a loss to the Celtics, Oubre scored seven points to go along with two rebounds and two assists in 14 minutes. He continued in a similar role until Dec. 16, when he had the best scoring game of his rookie season with 18 points (6-15 FG) against the Spurs. The very next game (Dec. 19), Oubre made his first career start in favor of Otto Porter, who was battling a thigh injury. Oubre ended up starting nine times in 17 games in the ensuing stretch, averaging 5.3 points and 3.7 rebounds over that span. His playing time waned afterwards as Porter got healthy, and Oubre finished the year averaging 3.7 points across 10.7 minutes while appearing in 63 total games. Nonetheless, he showed plenty of potential as a long-term "3 and D" player. Oubre's Wizards narrowly missed the playoffs with a 41-41 record, finishing 10th in the Eastern Conference.
