Despite losing Jayson Tatum in last year's Eastern Conference Semifinals against the Knicks, the Boston Celtics have exceeded expectations. The team is firmly in the playoff picture and currently holds the No. 2 seed in the East. On Sunday, the team will travel to Rocket Arena in Cleveland and take on the Cavaliers.
After missing the last four games due to right groin sprain, Donovan Mitchell is expected to return to the lineup to aid the Cavs in staying among the top four seeds in the Eastern Conference playoff picture. Mitchell has averaged a career-high with 28.5 PPG in a stellar 2025-26 campaign.
The matchup features one of the NBA's top offenses in the Cavaliers (119.1 PPG) against Boston's defense, which boasts the lowest PPG allowed (107.0). Boston also turns the ball over the least in the NBA, averaging just 11.4 TO per game.
Cleveland is looking to avoid being swept in the season series against Boston after losing the first three games. The presence of James Harden may help turn the tide for the Cavs, who can only hope they have what it takes in a potential future playoff matchup between the two sides.
