Mavericks forward Shawn Marion has been at the forefront of a stout Dallas defense that has stymied Gerald Wallace through five games in the series, helping propel the Mavericks to a 3-2 lead after Monday night's 93-82 victory at American Airlines Center.

"There's no way I'm going to let someone go for a real huge night," Marion said, summing up the one and only goal he carries into every game he plays.

After averaging 19.1 points per game and shooting 53.6 percent from the field over the final 13 games of the regular season, Wallace has been a no-show in the postseason, averaging an even-quieter-than-it-sounds 11.8 points per game and committing a team-high 14 turnovers.

Wallace is shooting 40 percent from the field (20-for-50) and 18 percent from three-point range (2-for-11).
