Only four franchises in league history have had such a run of dominance: the Minneapolis Lakers in the 1950s, the Boston Celtics in the 1960s, the Chicago Bulls in the 1990s, and the Los Angeles Lakers in the 2000s.
Miami does have many of the necessary pieces in place for such sustained excellence. With a strong team identity and multiple future Hall of Famers to lead the charge, the Heat have to be considered the odds-on favorites to win the title yet again next season.
But the league is getting stronger and the Heat are not improving in kind. Talent has coalesced among Miami's rivals for the title, and the three-peat bet is by no means a safe one.
