Yes agree here that Klay Thompson is a good defender aside from producing good contributions on Warriors' offense. If he will be like that next season, not sure. I think Steve Kerr is already aware of that and someone from the team should adjust and take their performance to a higher level to fill what's lacking for the Warriors. Since Klay is mostly catch and shoot, his offense will still be the same with not much difference or worrying that the same injury will be triggered.
And Green's defensive mentality might come back now that his lucky charm, the Splash Brothers, will now come back. They are still a decent team to consider compared to other teams.
They are all back! Steph, KLAY, Draymond and Andre' they are all part of the good era of warriors, now that they are reunited again the chemistry and that winning attitude will force everyone to work with them, they are now to be considered for the title contender, Coach Kerr just need to balance everyone.
The supporting cast are also better now, with Wiggins, Porter jr, lee, Bjelica, Toscano-Anderson they got fresh legs when the starters need some rest. Can't wait to see how they'll execute their offense to be their defense again. I love seeing all of them keep on moving until they find the right open man to take the shot.
