The 2015-2016 Warriors hold an undignified distinction of being one of the closest teams to winning a championship without actually winning it.
Game 7 of the 2016 NBA Finals was tied with less than 2 minutes left. We’re not quite talking about a buzzer-beater 3-pointer from the other team after being ahead by 2, but within Finals history, it ranks as one of the closer showdowns.
What instantly comes to mind as a comparison is the 2014 Finals between the Heat and Spurs. The Spurs were about to win the championship in 6 games, but Ray Allen had other ideas.
