Daniels appeared in 51 games for the Phoenix Suns in 2018-19, his second season with the team, with one start. Daniels averaged 6.2 points and 1.4 rebounds across 14.9 minutes per game in 2018-19. He played his best stretch of the season in early December. In four games between Dec. 4 and Dec. 10, Daniels averaged 14.0 points and 3.5 treys per contest. He saw extended minutes in March and April due to a variety of injuries to other players on the roster. During a five-game stretch from March 18 to March 27, he averaged 11.0 points and 3.8 rebounds per contest. The three-point specialist provided a scoring punch to the Suns' second unit, draining at least three three-pointers 10 times. His season highs in scoring and made three-pointers occured on Dec. 7 in a loss to the Heat, when he went 6-for-10 from downtown and scored 18 points. On Mar. 23, Daniels posted 16 points, three rebounds, five three-pointers, one dime and one block during a loss at San Antonio.

Daniels played for his fifth team in five seasons in 2017-18 after Charlotte traded him to Phoenix. His role continued to expand with the Suns as he played in the most games of his career (79) while notching his highest minutes-per-game mark (20.5). He started 15 games during the campaign, also a career high. Daniels cemented his place as one of the NBA's deadliest outside shooters by making 2.3 three-pointers per game, 25th-best in the league. He converted 40.0 percent of his shots from deep. Overall, Daniels posted career-highs with 8.9 points and 1.6 rebounds per contest. He also registered the best free-throw percentage of his career (87.5 percent). On Dec. 13, he scored 32 points against Toronto, the highest scoring output of his career. In that game, Daniels made 11-of-16 field goals including 7-of-10 from deep. It was one of three contests during the season in which the 6-foot-4 guard canned seven three-pointers.

After Daniels seemingly found a home with Charlotte in 2015-16, the Hornets traded him to Memphis in July. The move proved to be a boon to Daniels' career as he established career highs with 67 games and 17.7 minutes per contest with the Grizzlies. The guard out of VCU averaged 8.2 points and a career-best 1.5 rebounds per contest during the campaign. Daniels unleashed a flurry of three-pointers during the season as over 65 percent of his field-goal attempts came from beyond the arc. He finished the campaign making an average of 2.1 treys per contest. That mark ranked among the top 30 in the league. Daniels scored a career-best 31 points in a win over the Lakers on Dec. 3, making 6-of-12 three-point attempts. The performance was one of five during the season in which he connected on six or more treys. Daniels also appeared in all six games during the Grizzlies' first-round playoff series against San Antonio. He totaled nine points and five rebounds in those contests while making 3-of-9 attempts from deep.

Daniels thrived with Charlotte's Summer League squad in 2015, averaging 13.5 points per game and hitting over half of his three-point attempts in four games. He settled in with the Hornets during the 2015-16 campaign, playing 41 games and averaging 11.1 minutes per contest. The 6-foot-4 guard posted per-game averages of 5.6 points and 1.3 rebounds. Both marks were improvements over his previous campaign. He also averaged 4.5 three-pointers per 36 minutes, the second-highest mark in the league among players who played at least 20 games. Daniels again demonstrated expert marksmanship despite limited playing time as he converted 48.4 percent of his shots from deep. In a win over Sacramento on Jan. 25, he played 31 minutes and made a career-high eight three-pointers en route to a career-best 28 points. Daniels also established a career high with seven rebounds in that contest. He made three or more treys on seven other occasions. One of those performances was a 17-point effort against the Nets on April 8 in which he drilled five three-pointers.

Troy Daniels spent time with three different teams during his sophomore campaign in the Association. He began the season with the Houston Rockets, with whom he played 17 games and averaged 2.7 points per contest. Daniels was then traded to the Minnesota Timberwolves as part of a three-team trade. He logged 8.1 minutes per game in 19 contests with the Timberwolves and averaged 2.8 points. Daniels was traded again in February, this time to the Charlotte Hornets. The 6-foot-4 guard played only 16 seconds in his debut with the team but saw increased playing time at the end of the season. With Charlotte, Daniels finished the campaign playing an average of 12.3 minutes in 11 games. He responded by scoring 7.0 points per game and hitting 47.2 percent of his three-point attempts. In the team's final game of the season, Daniels played 29 minutes and scored a career-high 24 points. He converted 6-of-13 shots from deep in the contest and made all four of his free-throw attempts.

Troy Daniels was not selected in the 2013 NBA Draft but was scooped up by the Charlotte Bobcats and played for the team's Summer League squad. He averaged 6.7 points and 2.0 rebounds per game in the Summer League but was subsequently waived. Daniels then signed with the Houston Rockets shortly before the start of the regular season but was let go before playing in any NBA contests. He soon found a home with the Rio Grande Valley Vipers of the D-League, where he excelled. In 48 D-League contests, Daniels posted per-game averages of 21.5 points and 4.6 rebounds. He made 240 three-pointers during the campaign, far surpassing the previous D-League record. Daniels' sharpshooting caught the eye of the Rockets, who signed him to another contract. This time Daniels was able to compete for the squad, playing in five regular-season games and averaging 8.4 points in 15.0 minutes per contest. He demonstrated that his touch from deep in the D-League was no fluke as he averaged 2.4 three-pointers per game with Houston and shot 48.0 percent from deep. Daniels also got into four postseason games during Houston's first-round playoff series against Portland and posted per-game averages of 7.8 points and 2.2 rebounds while making 8-of-15 shots from three-point range.
