Draymond taunts Mavs rookie Dennis Smith Jr.: 'This ain't summer league'

Golden State Warriors forward Draymond Green is the reigning Defensive Player of the Year.

He's not letting some rookie get the best of him.

Green emphatically denied Dallas Mavericks guard Dennis Smith Jr. at the rim on Monday, then looked Smith dead in the eye and said "you'll never dunk on me" as play was stopped.

That trash talk continued after the game. Green came for the rookie yet again and even wished him luck in their next meeting.

"Yeah that sh-- ain't happening," Green told reporters. " ... This ain't summer league bro ... better luck next time."

Smith finished with 10 points and six rebounds and was a minus-34 on the night as the Warriors easily disposed of the Mavericks by a score of 133-103.
