As the NBA prepares for the 2026-27 season, the Western Conference is shaping up to be an absolute gauntlet. Yet, fresh off a hard-fought run to the championship stage, the San Antonio Spurs enter the preseason as the team to beat out West and claim the Larry O’Brien Trophy.
However, capturing the ultimate prize will be no cakewalk. Even if Gregg Popovich’s squad navigates the grueling western bracket, the Eastern Conference has reloaded with incredible firepower this offseason. If the Spurs return to the NBA Finals next June, these are the three Eastern Conference heavyweights that could pose the biggest threat to their championship dreams.
1. Toronto Raptors: A Nightmarish Defensive Juggernaut
If a high-profile trade bringing Kawhi Leonard back to Toronto ultimately goes through, the Raptors instantly transform from a young dark horse into a legitimate powerhouse.
Even before factoring in Leonard’s elite scoring punch and the health of Immanuel Quickley, Toronto boasts one of the most terrifying defensive identities in the league. Ranking fifth in defensive rating last season, the Raptors feature suffocating length across the board, anchored by Scottie Barnes—arguably the best non-big perimeter stopper in basketball. Coupled with the rising development of youngsters like Collin Murray-Boyles and Jamal Shead, their surplus of size, youth, and relentless energy would create a massive matchup headache for San Antonio.
2. Boston Celtics: Relentless Shooting and Masterclass Coaching
Boston has undergone a major roster makeover over the past few years, moving away from their 2024 championship core, but their status as an elite winning machine remains entirely intact.
Under the brilliant basketball mind of Joe Mazzulla, the Celtics operate with a system-first identity that never wavers, regardless of who is on the floor. With Jayson Tatum returning to anchor the lineup alongside Paul George and emerging rotation pieces like Hugo Gonzalez and Baylor Scheierman, Boston presents a unique stylistic challenge.
While the Spurs would hold a clear interior advantage against a frontcourt rotation featuring Neemias Queta and Mitchell Robinson, Boston’s unrelenting, high-volume three-point shooting can overwhelm any opponent. If the Celtics catch fire from deep, they have the firepower to completely outgun San Antonio.
3. New York Knicks: The Ultimate Unfinished Business
No list of Eastern Conference threats would be complete without the team that broke San Antonio’s heart this past June. The New York Knicks loom large as the ultimate obstacle, returning virtually the same roster that sent the Spurs packing in a grueling five-game NBA Finals series.
While recent historical trends suggest that immediate NBA Finals rematches are rare, neither franchise is showing any signs of slowing down. If the two titans collide again on the grandest stage in 2027, San Antonio will need to draw heavily on the harsh lessons learned from their previous defeat to flip the script.
Can Anyone Stop San Antonio?
Ultimately, the Spurs should rightfully open as favorites against any of these Eastern opponents, and their toughest overall battles will likely still come from within their own conference. However, none of these potential matchups would be easy pickings. If Victor Wembanyama and company want to claim the crown next season, they will have to go through some of the toughest, most tactical defensive and offensive units the East has to offer!
