Champion Cavs host Warriors in NBA holiday treat (AFP)

Cleveland and Golden State renew their rivalry in a Christmas Day clash that marks the first meeting between the NBA heavyweights since the Cavaliers' epic seven-game triumph over the Warriors in last season's NBA Finals. Both teams remain the class of their respective conferences, making the holiday showdown in Cleveland not only a reprise of the last two NBA championship series but also a possible preview of what would be an unprecedented third straight title duel between the two.
