Cooper Flagg explodes for 29-11-6 in Monday win over Miami

Fantasy basketball: Flagg's 40-minute, high-usage outing against the Heat pushes him into strong add territory in nine-category and points formats alike.

Cooper Flagg posted 29 points, 6 rebounds and 11 assists on Monday, October 26, adding 4 steals, 2 blocks and 2 threes on 12-of-23 shooting and 3-of-3 from the line in 40 minutes as a starter in Dallas's 113-109 win over Miami.

The line represents 65.7 fantasy points against 39.8 a game over last season (70 games), and it came with more minutes and shots than usual. Flagg is shooting 75.5 per cent true shooting at a 32.1 per cent usage rate through three games, averaging 25.0 points, 5.3 rebounds and 6.3 assists in 29.9 minutes a night. That carries legitimate value in both nine-category leagues and points formats, where he projects at 33.9 fantasy points a game.

Cooper Flagg

Flagg's 40 minutes were his highest total of the young season, and the 11 assists were his most in a game this season for a player who averaged 4.5 per game last season. The 29 points came on a season-high 23 field-goal attempts, and his four steals and two blocks gave him three games in a row with defensive category production. The five turnovers were the only blemish, though that number remains manageable for a forward running heavy usage.

Dallas has one game left this week, on Monday, before going dark next week. Flagg is averaging 33.9 fantasy points per game in default points scoring and ranks 60th overall in nine-category value, making him a strong add in both formats. His efficiency and defensive contributions, combined with the scoring and assist numbers, give him a well-rounded profile that plays across all league types.

What to do

• Add Flagg immediately in any league where he remains available, as his three-game sample shows top-75 production in both formats.

• Start Flagg on Monday in the Mavericks' final game of the week, then prepare for a week with no Dallas action.

• Monitor his minutes and usage through the early portion of the schedule, as the 40-minute outing suggests Dallas is leaning heavily on him in close contests.
