mmm it's an interesting question and one I answer having watched every game this season.
I dont agree with not playing "right". Kerr has always given his scorers a huge leash, and that hasnt changed. Its just now instead of Steph and Klay hoisting seemingly terrible shots, it's D Lo (a massive drop off in shooting). We are playing hard every night though, I'll given them that.
If we hadn't had the sustained amount of recent success, plus the obvious eye on next year, it would be a lot different. That said, I've been a fan of this team for 30 years so I've seen us look a lot worse and completely devoid of any hope (people forget how bad we were in to 2000s - eg 12 straight years missing the playoffs)
