Its too early to predict right now but one thing is for sure for me, if this duo will sync the whole season they can be a NBA Finals contender.
They are very close last season, but this season there's a lot of teams to beat in the West, they need to beat the Warriors, Clippers, and the Lakers if they want to be in the finals and if they can do that, I think it's almost guaranteed that they will have the NBA championship.
