2. Dallas Mavericks
Luka Doncic might have just recorded the best season from a 20-year-old of all-time. The sophomore player nearly averaged a triple-double, posting 28.7 points, 9.3 rebounds and 8.7 assists per game. His usage was off the charts but his impact on the Dallas Mavericks has made them a team that nobody wants to face in the first round of the NBA Playoffs.
Doncic is simply a master of everything. At such a young age, he has already developed a natural feel for the game that helps him dissect opposing teams at a high-rate. He is surgical with his decisions. His threat as a distributor and scorer makes him incredibly tough to game-plan for.
The Mavericks still have some work to do in finding support for Doncic. While Kristaps Porzingis is a promising prospect, his health concerns have made it difficult for the two to build any chemistry. Kristaps missed a chunk of the second half of the season, placing immense pressure on Doncic to produce.
The rest of the Mavs roster is lacking. They have a few quality guards in Tim Hardaway Jr., Seth Curry and Jalen Brunson but the team needs more firepower to truly be competitive. But, since their core is so young, the Mavericks will be an ongoing threat to the Golden State Warriors entering the new decade.
