Mavericks: 5 players who have changed dramatically this season

3 of 6

4. Dorian Finney-Smith

Dorian Finney-Smith has taken his game to the next level this season. He went undrafted in 2016 but earned a role on the Mavericks almost immediately because of his defense. Finney-Smith is capable of guarding elite perimeter scorers and never backs down from those matchups.

The 26-year-old needed to improve his shooting to earn more playing time, though. His 3-point percentage made a steady climb in each of his first three seasons, but he was a career 30.3 percent shooter coming into this year. It made him a virtual non-factor on the offensive end of the floor.

That changed this season. Finney-Smith is shooting 37.4 percent on his threes. That includes 38.8 percent on 3.8 catch and shoot attempts per game. He is sinking his wide open shots. Finney-Smith gets 3.3 tries each night and is connecting on 39.6 percent of them.

DFS is now the 3-and-D wing that every team covets. It has allowed him to earn a career-high 29.7 minutes per game and made Doe-Doe a full-time starter.

The Mavericks signed him to a three-year deal worth $12 million total last offseason which is shaping up to be one of the best bargain contracts in the NBA. Finney-Smith is the perfect role player as long as the shots keep falling at least at a league-average rate.
