Clippers is a more improve team this season, they don't only add Leonard in the line up, they also have Paul George.
IMO, they can compete with the Lakers or team Lebron and Davis as Clippers have a superstars too, and they have the best 6th man in the NBA which is an underrated player, I'm talking of Lou Williams, this guy is consistent, he can drop 20 or 30 points a night if PG and Leonard will both have an off night.
