Only the Raptors think they can win four of five and knock off destroyer of worlds LeBron James and the Cavaliers. Losing to LeBron in the East is just what teams do.
There is no shame in losing to LeBron James. Just look at a selected list of who has done it: Oklahoma City with Kevin Durant, Russell Westbrook, Serge Ibaka AND James Harden; San Antonio in the dying days of the great Tim Duncan, and the early ones of Kawhi Leonard; Golden State in the year they won 73 games, more than any team in history.
