The Cavaliers dominated quickly and then were up-and-down in extended garbage time of a 117-104 win at Boston in Game 1 of the Eastern Conference finals. Cleveland led by double digits the final three quarters and by 20 for nearly half the game. The Spurs' chances of upsetting Golden State nearly ran out when Kawhi Leonard got hurt, and Boston's bid to topple the Cavaliers didn't get off the ground in Game 1.
