J.R. Smith is a friendly guy.
So much so that he's apparently willing to give up a dunk for a hug.
That's what happened during the game against the Milwaukee Bucks Tuesday night.
The Cavs guard went to the sidelines to hug Bucks player Jason Terry with 2:57 remaining in the second quarter, allowing another player a wide open dunk.
When asked about the mistake by reporters after the game, Smith said: "I didn't even know I was in the game. My bad."
