It depends whether klay will be fully fit or not. Remember they made it to the finals without durant and they were in control of game 6 until klay went down.
Besides loosing Durant they also lost Iguodala and Cousins. Curry is somewhat injury prone so they better hope he stays relatively healthy next season or the might not even make the playoffs. As for the finals the Warriors got lucky that it actually went six games Toronto could have easily won that series in five games. But I like the final outcome loosing three games at home made it more embarrassing for the Warriors.
