In 2015, he took the Cleveland Cavaliers to the NBA Finals, without Kevin Love but lost to the Golden State Warriors in 6 games after losing Kyrie Irving after he had an ankle injury. The following year he again took the Cavs to the finals against the Warriors and made history when he led the Cleveland Cavaliers to an NBA championship after being down 3-1 games. No team had ever come back from a 3-1 deficit in the Finals before then. He had a historic moment where he blocked Andre Iguodala on possibly the game winning layup. The Cavaliers went on to lose to the Golden State Warriors the following season.
