VIDEO: Van Gundy isn't in the mood to high-five Reggie Jackson

Let the lip reading begin.

Even as the Detroit Pistons were closing in on a win against the Portland Trail Blazers on Sunday, head coach Stan Van Gundy saw no merit in celebrating on the sidelines with Reggie Jackson, who had every reason to be pleased after contributing 30 points, nine assists, and two steals in the contest.

Well known as a tough-minded and crusty bench boss, Van Gundy has built quite the archive of memorable moments.

Enjoy.
