The Dallas Mavericks started the season with 14 straight victories, one shy of the league record. They finished the regular season with 60 wins, a franchise best.

Now, against the Portland Trail Blazers, Dallas is on the brink of making some history it really wants to avoid: becoming the first NBA team to blow a 3-0 lead in the playoffs.

Portland has a chance to complete the unprecedented turnaround in Game 7 on Sunday. That they're going the distance is impressive in itself; only twice in league history had a team won three straight games after losing the first three of a playoff series.
