The Eastern Conference is a gauntlet this season. Nearly every team has bolstered its roster, and some are about to get critical players back from injury. For the Cleveland Cavaliers, the offseason narrative initially revolved around their failure to bring LeBron James home. But that story shifted dramatically when they swung a deal for Peyton Watson from the Denver Nuggets. The trade did more than just fill a positional need—it fundamentally altered the team's identity and ceiling. Let's break down why this Cavaliers squad can actually claim the East in the 2026-27 season.
**The Perfect Starting Five**
Cleveland's first unit can go toe-to-toe with any lineup in the league. It starts with a pair of All-Star guards: James Harden and Donovan Mitchell. Both can drop 20 to 25 points on any given night while also finding the open man. Mitchell scores at will, and Harden's step-back and foul-drawing tactics remain as effective as ever. Then there's Peyton Watson, the do-it-all wing they've been searching for at small forward. He shoots over 40% from three-point range, spacing the floor beautifully. He slashes and throws down dunks with authority. Defensively, he averages better than a block and a steal per game, making him a legitimate Swiss Army knife. Up front, Evan Mobley and Jarrett Allen round out the unit. Mobley proved his three-point shot is coming along, especially during the postseason, and he can block almost anything. Allen remains a model of efficiency from the floor and a steady rim protector. This is the best starting five Cleveland has put together since acquiring Mitchell.
**The Perfect Complements off the Bench**
The Cavaliers' second unit is built to thrive. Sam Merrill and Jaylon Tyson will lead the charge, each bringing elite shooting and solid defense. Both gained valuable starting experience last season and are ready to torch opposing benches. Mario Hezonja adds isolation scoring and playmaking. After five years away from the NBA, his performances for Croatia in FIBA qualifiers showed the player he has become. The 2024-25 EuroLeague MVP is expected to fit seamlessly into his role. Nae'Qwan Tomlin projects as a key contributor too—an athletic big who has been working on his shooting and will serve as a lob threat. And in the backcourt, the Cavs have no shortage of playmaking options: Craig Porter Jr., Tyrese Proctor, or Meleek Thomas. Proctor can light it up from deep, Porter is a skilled passer, and Thomas is a versatile piece. Any of them can enter the game and make the opponent pay. This bench unit is the perfect complement to the starters, giving Cleveland depth that few teams can match.
**They’re Hungry**
It’s no exaggeration to say that the Cavaliers' Game 1 loss to the Knicks ranks among the franchise's lowest moments. A commanding fourth-quarter lead vanished in an instant, a Sam Merrill three-pointer rimmed out to force overtime, and then Cleveland got pummeled in the extra session. They showed no heart over the next three games, getting swept. But this is a new team. Peyton Watson is now in the fold. James Harden has a healthy thumb. A now-married Donovan Mitchell signed a three-year extension. They want to bury that memory. The series sweep is fading, and making the Eastern Conference Finals is what they intend to remember this season. Even with all the powerhouse teams ahead of them, Cleveland matches up well on paper. And on September 2, paper is all we have to judge. Head coach Kenny Atkinson knows his team needs a strong start to quiet any doubts about his job security. He will have them ready. Beware of the Cavaliers—they are a legitimate threat to win the East. With the depth they've added since last season, every contender should keep an eye on Cleveland.
Article commentary
The Cleveland Cavaliers' case for Eastern Conference supremacy in 2026 rests on three pillars: a revamped starting five, a deep bench, and a burning hunger after last season's collapse. But objective analysis requires looking beyond the optimism. On paper, the starting lineup of Harden, Mitchell, Watson, Mobley, and Allen is terrifying. Harden's transition from Houston superstar to complementary playmaker has been smooth, and Mitchell remains one of the league's most explosive scorers. Watson's arrival addresses a long-standing weakness at small forward, adding both shooting and defense. Mobley and Allen form a formidable frontcourt duo, though Mobley's offensive consistency remains a question mark. His three-point improvement is promising, but he must sustain it under playoff pressure. The bench is deep, but relying on veterans like Hezonja, who has been out of the NBA for five years, carries risk. EuroLeague success does not always translate to the NBA's pace and physicality. Similarly, young players like Merrill and Tyson are unproven in high-stakes postseason minutes. The wildcard is health. Harden has a history of hamstring issues, and Mitchell has missed time with various ailments. If either goes down, the Cavs' offense could stagnate. Defensively, the team is solid, but switching against elite perimeter-oriented teams like the Celtics or Bucks could expose Allen's lateral quickness. Beyond the roster, the Eastern Conference is deeper than ever. The Boston Celtics are the defending champions. The Milwaukee Bucks have Giannis Antetokounmpo and a retooled supporting cast. The Philadelphia 76ers, New York Knicks, and Miami Heat all made significant upgrades. The Cavaliers' path is not easy. Their Game 1 collapse against the Knicks revealed a team that can lose composure under pressure. While that loss may fuel them, mental toughness is not built overnight. Kenny Atkinson's coaching will be scrutinized. He has a tendency to experiment with rotations, which could backfire in tight games. The Cavs also lack a true closer beyond Mitchell and Harden—both of whom have had their moments of playoff struggle. What gives Cleveland an edge is versatility. They can play small with Watson at the four, or go big with Mobley and Allen. They have shooters, creators, and defenders. If all pieces click, they can beat anyone. The 2026 season will test whether this collection of talent can overcome its historical baggage and the rising tide of competition. The Cavaliers are a legitimate threat, but they are far from a lock. The East will be a war, and Cleveland will need to win battles on both ends of the floor to emerge victorious.
