I'm pinning this (so far) crap fest of a season mostly on two individuals: Frank Vogel and James Jones.
Vogel is clearly just not a good coach at all, and quite possibly utterly clueless. It's apparent he was just along for the ride with the Lakers, and I guess was hoping to repeat that here. Unless the Suns make some massive (and unforeseeable) turnaround by the end of the season, I'm guessing he'll be fired after just a year, which is pretty ignominious.
And I don't think James Jones knows what he's doing either. He can't construct a roster, and any of the guys we dumped for nothing the past two seasons (Saric, Payne, Crowder) would be coming in handy right about now. And I know Crowder was part of the Durant trade, but he didn't have to be... and he was an asset until Monty and Jones decided to get in a pissing match with him.
The team is definitely a mess, but it's not by accident. We'll see if they ever get healthy, how much of a difference it makes. But just watching the inexplicable nonsense on the court from veteran players who you have to believe would know better, tells me there's something going on besides just injuries and guys needing time to mesh.
