INDIANAPOLIS - FEBRUARY 12: Paul George #24 of the Indiana Pacers handles the ball against the Dallas Mavericks at...
MVP: Monta Ellis did a little of everything, recording 23 points -- including 11 in the fourth -- six assists and nine rebounds. Ellis came up huge in the fourth, and not just because of his aforementioned scoring. He snagged several key defensive rebounds that prevented any hope of an Indiana victory.
X factor: Brandan Wright was the key cog for Dallas in the pivotal fourth quarter. His stats won't necessarily show it, but he made several nice defensive plays, in addition to his seven points and five rebounds.
That was ... chippy: First, Lance Stephenson gets a technical foul, followed closely by Jose Calderon. Then, Dirk Nowitzki and David West exchange words, as well as elbows. Not to be left out of the action, George Hill and Jose Calderon start exchanging unpleasantries. This was not a friendly game of basketball.
