Cleveland Cavaliers star Donovan Mitchell delivered a defiant claim following his team's loss to the Boston Celtics.

DETROIT — In a season where Donovan Mitchell has thrived by balancing scoring with playmaking, helping his teammates grow around him, the Cavs asked him to channel his “Spida” moniker and shoulder the offensive load to keep them close against the Celtics on Tuesday.

Mitchell's dunk over Kristaps Porzingis failed to set the tone for the Cavaliers, who fell at home to the Celtics.

Mitchell drove to the rim, jumped up, and put Celtics forward Kristaps Porziņģis on a poster with a highlight jam. The best part of this play was watching Mitchell's Cavaliers teammates react to the dunk.

Donovan Mitchell just threw down one of the biggest dunks in years for the Cavs during Tuesday night's game against the Celtics.

Nearly five minutes into the contest, the Cleveland Cavaliers guard attacked the rim after splitting two defenders at the top of the key.

Ever since he won the Slam Dunk Contest during his rookie season, Donovan Mitchell has established himself as one of the league's best dunkers -- particularly among smaller guards. He added to his resume on Tuesday night with a potential dunk of the year candidate.

The Cleveland Cavs and Boston Celtics meet in both an NBA playoff rematch from last year and a potential 2025 Eastern Conference Finals preview.

This was bad news for Kristaps Porziņģis. Donovan Mitchell put Porziņģis on a poster with a power slam over the 7-2 center early Tuesday to ignite the Cleveland home crowd in a matchup against the Boston Celtics.

The Cavs could be without Donovan Mitchell as they hit the road to take on a familiar divisional rival: the Pistons.
