Question: The 2011–12 Oklahoma City Thunder advanced to which championship series against the Miami Heat?
Context: The 2012–13 Oklahoma City Thunder season was the 5th season of the franchise in Oklahoma City and the 47th in the National Basketball Association (NBA).  After their trip to the NBA Finals, despite losing the Finals to the Miami Heat in five games, the Thunder improved on last season's output, winning 60 games, earning them the top seed in the Western Conference.  The first round pitted the Thunder against the eight-seeded Houston Rockets, led by James Harden, a former Thunder player.  Despite a season-ending injury to Russell Westbrook in game 2, the Thunder still managed to breeze past the Rockets in six games, to advance to the next round, where they faced the Memphis Grizzlies.  The absence of Westbrook, however, affected the Thunder and they would end up losing to the Grizzlies in five games.

The 2011–12 NBA season, the 66th season of the National Basketball Association (NBA), began with the signing of a new collective bargaining agreement (CBA) between the owners of the 30 NBA teams and the NBA's players.  The previous CBA, which was ratified in 2005, expired at 12:01 AM EDT on July 1, 2011, resulting in a lockout.  With the new deal in place, the regular season was shortened from the normal 82 games per team to 66, because of nearly two months of inactivity.  The season began on December 25, 2011, and ended on April 26, 2012.  The playoffs started on April 28 and ended on June 21 when the Miami Heat defeated the Oklahoma City Thunder in Game 5 of their series, 121–106, winning the Finals, 4–1 and to capture the franchise's second NBA title.

After the draft, his draft rights were immediately traded to the Oklahoma City Thunder, the NBA affiliate of the 66ers.  However, the Thunder did not sign him to a contract and Williams returned to the D-League with the 66ers.  On February 19, 2015, his draft rights were traded to the New Orleans Pelicans.

The Thunder continued to build on recent success in previous years by making the NBA Playoffs, defeating and sweeping the defending NBA champions, the Dallas Mavericks in the First Round, the Los Angeles Lakers in the Semifinals, and finally, the San Antonio Spurs in the Western Conference Finals to advance to the NBA Finals.

The Mavericks won the NBA Championship after defeating the Miami Heat in 6 games in the 2011 NBA Finals.  The Mavs playoff run came with a 6-game first round series against the Portland Trail Blazers, a series in which the Mavericks blew a 23-point lead in Game 4, but still won the series.  In the conference semi-finals, the Mavericks run was motivated with a sweep of the champions of the previous two seasons, the Los Angeles Lakers.  The series against the Lakers also became the birth of the Mavericks Royal Blue-Out games in the AAC, with almost all fans wearing T-shirts that read "The Time is Now".  In the Western Conference Finals against the Oklahoma City Thunder, the Mavericks won the last 3 games winning by 4th quarter comebacks, to win their second Western Conference Championship, and a trip to the NBA Finals for the first time since 2006, with a rematch against the Heat.  Following a disappointing Game 1, the Mavericks pulled the biggest comeback in NBA Finals history in Game 2 to even the series at 1 game each.  After a loss in Game 3, the Mavericks won the last two games in Dallas to take a 3–2 series lead heading to Game 6 in Miami.  The Mavericks won their first NBA Championship in Game 6 to clinch the first major sports championship in the Dallas-Fort Worth area since the Dallas Stars in 1999, and the first title in Mavericks franchise history.  The Mavericks are the third team to win an NBA title in the state of Texas, joining the Houston Rockets and San Antonio Spurs.  The Mavericks are also the third team to win a major sports championship in the Dallas-Fort Worth area, joining the Dallas Cowboys' five Super Bowl titles and the Dallas Stars' only Stanley Cup, leaving the Texas Rangers as the only team to not win a major sports title in the area, as they have not won the World Series.
