The Mavericks raised their championship banner prior to their Finals rematch with the Heat on Christmas Day, but in what would soon become a mirror image of the 2006–07 Miami Heat seasons eventual failed title defense, Miami blew them out in a 105–94 loss, marking Dallass first regular-season loss to Miami in eight seasons. Things did not get better for Dallas after starting the season 0–3, losing to the Thunder in a playoff rematch on December 29. As the calendar turned to 2012, the Mavericks won 13 of 18 games in January, but they posted a 22–22 record the rest of the way, eventually finishing 7th with a 36–30 record, their lowest finish since the 2007–08 season. Nowitzki produced 21.6 points, 6 rebounds and 45.7% shooting, his lowest numbers since the 2000–01 season. Meanwhile, Odom proved to be a bad fit for the Mavericks, and they decided to sit him out for the final two months of the season.

What year did Dallas see their first loss to the Miami heat during regular season in eight years?
