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

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.

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