IMHO it's not effort that holds this team back.
All game long, I watch guys overcommit on help, help when they shouldn't, lose guys off ball, miss rotations, miss extra passes, force contested shots, and miss assignments on the glass. Effort is an element to some of these things for sure, but overall I think the biggest problem is that we just don't know how to play together. We don't trust each other at all. We aren't on the same page together at all.
I've been in Stevens' corner but admittedly I'm wavering. I'm not used to seeing this out of his teams. In the past, his teams have been characterized by disciplined defense that often outweighed the sum of its parts and an egalitarian offense with a lot of shared responsibility. This year I don't see any of that. I do not think he is a bad coach. I think he has his flaws, but is a good coach overall. But I'm opening to the idea that this group of players just isn't listening to him. And if that's the case, maybe it's time that we find a new voice.
For the record, that may not solve anything. It may very well be an issue with this group of players, rather than this coach. But the grass on the other side of that fence is starting to look pretty [dang]ed green to me, compared with where we're sitting now.
