Celtics and Cavaliers Open Preseason With Plenty of Questions

Cleveland's preseason opener should reveal more about rotations and roles than about the standings.

Preseason basketball rarely offers clean answers, and Cleveland's 2026-27 opener against Boston on Oct. 8 should be no exception. The Cavaliers are at home for their first exhibition, which means experimental rotations, uneven minutes and plenty of lineup tinkering. The result matters far less than what each coaching staff learns about its group.

Boston is the more intriguing test case. With Jaylen Brown gone, the Celtics are entering a new era built around Jayson Tatum and Paul George, with a retooled roster under Brad Stevens. Derrick White has pointed to the team's depth, saying there are many ways to win and many players who can step up. That fits an exhibition setting, where a deeper group can spread the workload and keep the pressure off any one scorer. Tatum and George will set the tone, but contributions from the supporting cast may decide how smooth Boston looks.

Cleveland's biggest storyline is how James Harden and Donovan Mitchell share the offense. Both need the ball to be at their best, so Kenny Atkinson will be sorting out usage even in a game with little at stake. The defensive side is murkier because Peyton Watson, expected to take the toughest perimeter assignments, is a game-time decision with a hamstring injury. If he sits, Cleveland loses its best-suited answer for Boston's wings.

Both teams ended last season on losing streaks, so neither arrives with momentum, and both will want a cleaner start. I give Boston the edge because its structure looks clearer, with Tatum and George leading a deep group, while Cleveland is still working through its backcourt balance and a questionable Watson. Expect a choppy, rotation-heavy game that Boston controls late.

Prediction: Celtics 112, Cavaliers 106.
