I would agree that it's the combination of Klay and Steph that is so dangerous.  Steph is insane so he can get his own shot, but when you give him another shooter like Klay it opens up the floor and gives him a chance to shoot open jumpers at an outrageously accurate clip.  I think given that Klay was never really dependent on his athleticism he'll probably come back as good as ever, but Draymond hasn't kept up his game as well in the years since the Splash Brothers have dominated the league.  While I think they'll always be a threat so long as they're together, I think the lightning they had trapped in a bottle is out, and I don't see them winning another championship together.
