I have flip flopped on Westy more than any other factor surrounding this team. At this point, I'll say keep him, until I hear something concrete, and a substantially better coaching option. Maybe substantially is the wrong word, but I wouldn't consider anyone else unless it was a definite upgrade.
There have been many things Westy has done which I have disagreed with, and still believe with a better coach, we'd have a better record. But Tyreke hadn't been healthy all year until the recent 5 game stretch. Many here acted like Tyreke just lost his skillset over the summer, but I always mantained that the problem was his foot. That set us back from the beginning, and obviously had an affect on Westy, as it would any coach. Dally was injured throughout training camp, and it took a little while for him to get his rhythm. While I do blame him for some of the inconsistent play from our young sf's, mainly not giving them consistency or much confidence in Donte's case, I can't blame him for none of our sf's being starting caliber nba sf's. We don't have one on this roster. It's also tough when Tyreke is out, and we hadn't traded for Thornton yet, and you're forced to give guys like Head and Pooh 30+ minutes because of zero depth at the guard positions.
This was the year i was going to judge whether or not we should keep Westy, but I can't objectively say he's been given a fair shake. Not with the roster he was dealt, along with the injuries we've suffered. But that certainly coesn't mean I agree with everthing he does. Far from it.
But right now he has a more talented roster than 2 months ago, and a healthy Tyreke, and a more mature Cousins. He settled into a rotation, and the guys seem to be not only playing very hard for him, but are enjoying playing for him as well. Omri being the obvious exception. As a result, we're winning. I agree with everyone who thinks it can be very risky to make a switch now, with guys finally settling in, understanding their roles, as we continue to build momentum. I want a Dally/Cousins starting duo next year. Would another coach? I like Tyreke/Thornton together, and would like to see that next year as well. Would another coach? I'm also worried about how another coach will handle Cousins. There are just too many ways to screw this up at the moment. That's why if we make a change, Petrie/Maloofs better be 100% sure it will work out better. There is absolutely no reason to take an unnecessary risk right now.
I'd also say, despite any feelings I have, if i was betting, I'd bet that Westy is the head coach on opening night next season. And I would say it isn't close to 50/50. More like 80/20 in favor of him staying around.
