The Cleveland Cavaliers Rivalis the Golden State Warriors. This rivalry was created back in the 2015 playoffs, where both teams embarrassed their opponents until they met in the 2015 Championship. Everyone knew they would be meeting in the Championship since the start of the playoffs. The Championship series went to six games when the Warriors won their first championship since the 1970s. The next season the Warriors broke a record for most regular season wins, and once again met the Cavs in the Championship. This time the Cavs won in seven games bringing them their first Championship ever! The rivalry has been going on ever since, and is not looking like stopping anytime soon.
