It's far too early to be writing off the Cavs.
I don't think cats in here are even watching Cleveland play like that. They've got great depth and an incredibly balanced attack; it didn't help they suffered a lot of injuries last season, but their offense is remarkably better under Atkinson. He's actually adopted some of the Warriors system into the Cavs offense, most notably using Mobley in similar fashion to how GS uses Draymond, by using him as an initiator to drag out his opposite to open up the floor a bit more.
I wanna see how they respond to some adversity first before making any projections on how far they'll go in the postseason. They've got the pieces but it remains to be seen if they have the mental fortitude as a group.
