Too early to talk who will be the champion next season. Players are still weighing where or which team they will go. Still the Golden State Warriors will be the barometer of all the teams in the NBA. Lebron James will be recruiting an army of star players so he could dethrone the Warriors this year.
Lebron dont have a plan to defeat the GSW this year, as you can see, they're signing vet players for a 1 year contract. Next year there would be another set of superstars who will be on the free agency including Leonard. In 2019 the Lakers will have enough cap space to sign superstars. Just like Magic planned every step he can to bring back the Lake show on stage.
