That's the important thing, as long as Kawhi and Harden are healthy the chance is nit by far, knowing how those two scorers shared the court they've got a good blend of chemistries, theyjust fell short last season but now that Kawhi being kawhai again, together with Zubac, Collins and Beal that's a decent core it's more now on the side of the coaching staff if how they'll be playing those stars together and what system to run that will going to be fit on both defensive and offensive sides.
I’m impressed that Kawhai is not injured on the playoffs despite having a tough battle which normally sent him to injury zone due to his intense physical game when he is playing.
I have no doubts with Kawhi capabilities but Harden is always choking on crucial games especially on playoffs. He is only good on regular season or in playoffs matches that they have clear advantage against the other team.
Harden always choke when he is needed the most.
