In 2014, LeBron James and the Miami Heat beat the Indiana Pacers in the Eastern Conference Finals to go to their fourth straight NBA Finals. In doing so they ended a rivalry that had persisted for three seasons, and also my nightmares of Danny Granger, Paul George and Roy Hibbert.
From 2012-2014 the Pacers and Heat matched up in the NBA Playoffs three times. Once in the Eastern Conference semis and twice in the Eastern Conference Finals. Over that period of times, the Heat/Pacers rivalry delivered us classics.
