2011-12 San Antonio Spurs
With their victory against Oklahoma City in Game 2 of the 2012 Western Conference finals, the Spurs set an NBA record for longest winning streak bridging the regular season and playoffs. That marked their 10th consecutive win to open the playoffs, on the heels of a 10-0 regular-season finish. (San Antonio lost Game 3 to the Thunder.) Tim Duncan and Co. also had two separate 11-game winning streaks during the regular season, when they used their venerable Big Three, young role players and the league's top offense to tie Chicago for the best record at 50-16.
