Now the tournament will advance to the knockout rounds, with eight teams competing in a single-elimination tournament for the first NBA In-Season Tournament title. The East side of the 2023 NBA In-Season Tournament bracket will include the Bucks, Pacers, Celtics and Knicks while the West will feature the Lakers, Kings, Pelicans and Suns. The quarterfinals take place on Monday and Tuesday with the higher seed hosting each matchup while the semifinals and finals take place in Las Vegas on Dec. 7 and 9.

Boston is the +300 favorite (risk $100 to win $300) in the 2023 NBA In-Season Tournament odds, followed by Milwaukee (+340), Los Angeles (+550) and Sacramento (+550). The Suns (+650), Pelcans (+1200), Pacers (+1300) and Knicks (+1400) are the NBA In-Season Tournament longshots but anything can happen when it's single-elimination, winner-take-all.

Top 2023 NBA In-Season Tournament predictions

One of the surprising NBA In-Season Tournament bracket predictions from the model: It is fading the Celtics even though they're the favorites to win it all at +300. The Celtics are off to a 15-4 start that puts them in first in the East but they'll be without Kristaps Porzingis (calf) as they take on the Pacers in the quarterfinals on Monday.

Boston has struggled away from home this year even when it has been at full strength. All four of the Celtics' losses have come on the road, including a 113-96 loss to Orlando in group play.

Boston fortunately drew a Chicago squad that had already been eliminated and had nothing to play for in the final group-stage matchup and that led to a 27-point win that helped the Celtics beat out the Magic and Nets on point differential. However, now they'll travel to Indianapolis to possibly take on arguably the best point guard in the NBA over the first quarter of the season Tyrese Haliburton, though he is listed as questionable (illness). The model only has the Celtics winning their first-round matchup 50.5% of the time and winning the tournament only 18.7% of the time. See which other teams to pick here.
