​The OKC Thunder fell short of defending its NBA championship last season.Injuries ultimately derailed OKC, which found itself without Jalen Williams and Ajay Mitchell down the stretch of the playoffs. It ultimately lost in seven games to San Antonio in the Western Conference finals.But both players are now healthy entering the 2026-27 NBA season. And despite trading away Lu Dort, Isaiah Joe and Aaron Wiggins this summer, the Thunder is poised to compete for a championship once again. It’s tied with the Spurs for the best title odds in the league, according to BetMGM.There are plenty of other contenders in the mix as well. Here are the top 10 biggest threats to OKC this season:OKC Thunder schedule release 2026-27: See all 82 NBA game times, TV channels10. Indiana PacersMiami traded for Giannis Antetokounmpo. Toronto traded for Kawhi Leonard. The Los Angeles Lakers revamped their roster to give Luka Dončić more support.All of those teams have a case to make this list, but don’t forget about Indiana. The Pacers are only a little over a year removed from reaching Game 7 of the NBA Finals, and Tyrese Haliburton is now healthy after being sidelined last season by a torn Achilles. Ivica Zubac is also an upgrade at center, and Kelly Oubre Jr. is a new addition to the bench.Indiana only has the 15th-best championship odds (+6600), according to BetMGM, so I’m higher on it than most. But it wouldn’t surprise me if the Pacers made another run to the Finals and put up a good fight.9. Houston RocketsFred VanVleet tore his ACL right before the start of last season, forcing Houston to lean heavily on second-year guard Reed Sheppard. Steven Adams was also limited to just 32 games, and his absence was felt on the glass.But Houston still managed to finish fifth in the West with a 52-30 record, and it’ll now get both guys back. It’ll also have Marcus Smart in the mix, giving the team another veteran guard it can count on.Floor spacing is still a concern. But Houston has the size to cause matchup problems for OKC, along with every other team, and it’s much deeper than last season.8. Detroit PistonsDetroit went from 14-68 to 44-38 to 60-22 throughout the past three seasons. It’s one of the biggest teams on the rise thanks in large part to Cade Cunningham, a gifted scorer who has cemented his superstar status.Losing Tobias Harris this summer hurts because he provided shot creation for a team that’s shorthanded in that department. But the additions of John Collins and Isaiah Joe are good ones.Maybe this is the year the Pistons finally break through after reaching last season’s Eastern Conference semifinals. And if they do reach the Finals, they could muck up enough games with their physical play style to give themselves a shot.More: NBA offseason grades for every East team: Were 76ers, Heat biggest winners?7. Boston CelticsSome people might be quick to dismiss Boston because it traded away Jaylen Brown this summer. And while his production will be tough to replace,
