What happened: Cleveland is marking the 10th anniversary of its 2016 NBA championship, when the Cavaliers became the first team to overcome a 3-1 deficit in the Finals. They did it against a Golden State Warriors team that had just set the regular-season record with 73 wins.

Why it matters: The combination of the deficit and the opponent is what makes the case. No other champion has had to climb out of a 3-1 hole in the Finals, and few have had to beat a team that won 73 games to do it. That degree of difficulty is why the run still stands above the rest a decade later.
