2025 Fantasy Outlook
Flagg's storybook rise to the NBA started when he became the first freshman ever to be named the Maine Gatorade Player of the Year, leading Nokomis Regional to the state title in 2021. He transferred to a national powerhouse, Montverde Academy, the following year, winning the 2022 USA Basketball Male Athlete of the Year and the 2024 National High School Player of the Year. The awards kept coming in college, including ACC Rookie of the Year, ACC All-Defensive Team and National College Player of the Year during his lone season at Duke. Flagg has the height, strength and instincts to play down low as a shot blocker, but he also has the quickness and athleticism to lock down on the perimeter. Plus, his motor never wanes on that end of the court. Flagg put up elite offensive numbers at Duke and has immense potential, but is far from a polished prospect. However, the phenom showed vast improvements early at the collegiate level and eventually emerged as Duke's go-to offensive player in clutch situations. There's nothing Flagg can't do on a basketball court, which is why he was the consensus No. 1 overall pick, but he'll have to continue to improve to live up to his lofty expectations. With Kyrie Irving slated to miss at least the first half of the season, Flagg will be forced into uncomfortable offensive situations early in his career, but the Mavericks' new franchise player's ability to stuff the stat sheet makes him an intriguing fantasy option, even if there are concerns about how his offensive game will translate to the NBA.

Personal Bio/PreCareer Summary

Flagg was the first freshman named Maine Gatorade Player of the Year after leading Nokomis Regional to the state title in 2021. Following the storybook season, he transferred to Montverde Academy and continued to dominate, winning 2022 USA Basketball Male Athlete of the Year and 2024 National High School Player of the Year. Flagg continued to collect awards in his lone collegiate season, including ACC Rookie of the Year, ACC All-Defensive Team and National College Player of the Year. Flagg averaged 19.2 points, 7.5 rebounds, 4.2 assists, 1.4 steals and 1.4 blocks in 30.6 minutes across 37 games. He was efficient in every phase, posting 48/84/39 shooting splits on 13.4 field-goal attempts, 3.6 three-point tries and 5.8 free-throw trips per game. Flagg was Duke's best player all season, leading the Blue Devils to a Final Four appearance before losing to the Houston Cougars. Flagg's elite defensive versatility separates him from the rest of the 2025 class. He has the height, strength and instincts to play down low as a shot blocker, but he also has the quickness and athleticism to lock down on the perimeter. Plus, his motor never wanes on that end of the court. Offensively, Flagg, who put up elite numbers at Duke, is far from a polished prospect, but the potential is glaring. Flagg showed vast improvements early at the collegiate level and eventually emerged as Duke's go-to offensive player in clutch situations. There's nothing Flagg can't do on a basketball court, which is why he's the consensus No. 1 overall pick, but he'll have to continue to improve to live up to his lofty expectations. Flagg's floor is higher than most projected No. 1 overall draft picks due to his defensive prowess and versatility, but if he's able to unlock his full offensive potential, watch out. For his size, Flagg is an elite shooter, passer and ballhandler. However, compared to the elite shooters, passers and ballhandlers at the NBA level, Flagg still has plenty of room to grow. If he turns into a sharpshooter, Flagg could look like a more athletic Larry Bird (6'9, 220) in a few years. If he focuses on his paint scoring and passing, Flagg may have an offensive game similar to Franz Wagner (6'10, 220) or Scottie Barnes (6'7, 225). If his 1-on-1 game flourishes at the next level, Flagg would likely start drawing comparisons to Jayson Tatum (6'8, 209). Flagg will start from Day 1 and likely be a franchise player.

Posts team-high 20 points in win
FDallas Mavericks
January 7, 2026
Flagg racked up 20 points (8-15 FG, 2-5 3Pt, 2-2 FT), eight rebounds, six assists and one steal in 35 minutes during Tuesday's 100-98 win over the Kings.
ANALYSIS
Flagg put together a solid all-around line, marking his first 20-plus point total of 2026 in the narrow win. He fought out of a shooting slump that limited his production against the Rockets and Pistons earlier in the month, but his secondary contributions have remained solid with no significant drops. Flagg is averaging 18.9 points, 6.5 rebounds, 4.2 assists and 1.2 steals, and he has missed only one game this season.
