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

Celtics' big man Kristaps Porzingis rotated to help and contest Mitchell at the rim. Porzingis jumped and got his arm up, but Mitchell cocked his arm back and slammed the ball down over the seven-footer, which brought the full crowd at Rocket Mortgage FieldHouse to its feet.
