The Mavs entered the 2011 NBA Finals as underdogs, due to Miamis "Big Three" coming together during the course of the 2010–11 NBA Playoffs. After dropping game one in Miami by a score of 92–84, the Mavs needed more than just Nowitzki to score, with Nowitzki even calling out teammate Jason Terry earlier in the playoffs. In the fourth quarter of game 2 with the Mavericks trailing 88–73, Dallas was desperate to avoid a 0–2 heading back home. Dallas then staged a comeback, going on a 22–5 run to end the game, and stun the Heat with a game two victory, evening up the series at a game a piece. After the series shifted back to Dallas, the Mavericks lost in game 3, with Nowitzki narrowly missing the potential game-tying shot, by a score of 88–86. Dallas yet again showed their resiliency, winning a pivotal game 4 with Dirk hitting multiple big shots down the stretch to tie the series at two. Game 5 was a bit of an offensive showcase, with both teams breaking 100 points for the first time in the series. Jason Kidd and Jason Terry both hit huge shots down the stretch and the Mavericks defeated the Heat 112–103, putting them one game from their first ever NBA title. Three nights later, the Mavericks captured their first ever NBA title with a 105–95 victory, completely reversing what had happened in the 2006 NBA Finals. Nowitzki scored 21, including 18 in the second half, and Terry provided 27 points off the Dallas bench. Nowitzki was so emotional after the game that he headed to the locker room before the game had concluded, and had to be coaxed back onto the floor for the NBA Championship trophy presentation. Nowitzki took home the NBA Finals MVP honors, after averaging 26 points a game during the series, shedding the Mavericks label as "soft", and putting an end to the Mavericks post-season futility.
