Just as Jason Garrett changed the culture of the Cowboys in 2010, Tyson Chandler transformed the Mavericks' defense. After a decade in which the team tried to out-offense opponents as its only path to victory, the Mavericks suddenly won games 91-89 instead of 121-119. In the middle of the identity switch was the Mavericks' defensive anchor, a free-agent center who blocked shots, took charges and barked instructions to teammates en route to earning third place in the NBA's Defensive Player of the Year voting. Dirk was Dirk and Jason Kidd was almost better than ever, but the Mavs don't win a championship without Chandler in the middle.
