Two points:
1) I think the coach's performance is directly related to the players' performance, and while it's true that Westphal's rotations are problematic (I'm being nice), there are certain players who have not contributed at the level they were expected to this season. There have also been injury issues that have held some back. Either way, to say that we're losing a lot of games is true, but it's not entirely the coach's fault, and it never is.
2) My entire assertion that we shouldn't fire Westphal is not a defense of Westphal in and of itself. I'm not saying that we should give him a chance to prove himself, although I do think that firing a coach 100 games into his tenure is counter-productive (most coaches with young teams have a rough go in their first 100 games). I'm saying that, given the history of this team since we fired Adelman, there has been zero chemistry built, zero continuity established... There's no voice on the team, no identity that you can point to and say "that's what the Sacramento Kings are all about." No significant stretch of games where we actually looked like we were starting to come together and get something going. Nothing.
And if you fire Westphal now, you absolutely guarantee that that four or five year stretch of zero consistency continues for the rest of this season. While it's entirely possible that we could find our own Scotty Brooks if we handed the keys over to someone else right now, that's the exception to the rule. You need look no further than Kenny Natt to understand how teams usually play under interim/assistant head coaches when the main guy who ran the training camp and has been trying to stamp his identity on the team is booted after a few games. Natt is the rule.
On the flip side, it's hard to say that we're establishing any continuity when we have a different lineup/rotation every other game. Injuries have necessitated some of the changes, but for the most part, it's just Westphal saying "I think I'll try this tonight," and that's not good. It shows in our play, too. What is entirely possible, though, is that we could be looking at the makings of a set lineup/rotation that will begin to be established after a few games. We're only 18 games into this season, and about half the team is new. There's a learning curve there. Not defending Westphal's haphazard rotations, just wondering aloud if he's going to settle on something eventually.
