I want to take things a bit of a different direction now:
With KP out, is this team actually that loaded?
These are the changes:
TL -> Kornet
Smart -> Jrue
Brogdon -> PP
Grant -> Hauser
With the exception of Jrue, people wouldn't call those big changes/upgrades. (I think current PP is an upgrade on Brogdon because PP actually plays defense, but you get the idea.)
Last night was a pretty similar scenario to playing Philly in Game 1 without Harden last year. In that game, they came out incredibly flat, didn't execute for long stretches, and ultimately lost. Also happened a couple times against Atlanta, and even the win to close that out in Game 6 was tough.
This is the same key guys, but they've leveled up massively in ability to focus and execute. We attribute it to "super team" because of KP and Jrue, but it's clearly something more than that at this point.
