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.

A matchup of the two best teams in the East featured one of the dunks of the year Tuesday night. 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.

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