A huge dunk from the home team can change a game's momentum. It gets the team fired up, it gets the crowd going crazy and, sometimes, it forces a opposing coach to call a timeout. 

When Dallas Mavericks center Greg Smith posterized the Oklahoma City Thunder at the American Airlines Center on Sunday, OKC head coach Scott Brooks elected not to call timeout. Then he watched Reggie Jackson turn the ball over and Chandler Parsons rise up for another rim rocker on the break. 

Fun times. For everyone but the Thunder, that is.
