Being a superteam can be hard. This is a lesson that has been passed on from the 2010-11 Miami Heat to the 2012-13 Los Angeles Lakers to the 2014-15 Cleveland Cavaliers — and one that the LA Clippers are grinding through this season. Their 30-13 record heading into Tuesday’s game at the Dallas Mavericks is very good. They’ve beaten the conference-leading Lakers twice already. Most sportsbooks currently have the Clippers as the co-favorite if not the favorite to win the title. But to look at the record and Vegas odds would belie their journey thus far. It has not been a smooth season.
