We've used Luc a decent amount as a 2 guard this season, and Ariza has played a ton of 2 guard. It doesn't really matter that much, because there aren't many 2 guards that can burn us for doing that, and it's worked for us well so far. The real question is (outside of depth in case of a very bad emergency) why should we change our rotation significantly at all?
I'd like for us to get to a 10 man rotation at least, either adding a backup guard or yet another sg/sf who is defensive-minded. It'd be cool if Zhou could play solid defense with his height, but he's still got quite a bit a way to go. heck, i'd like to get beverly back now haha (though I know it's probably not possible). But it'd be fun, and as critical as i've been of him in the past, he deserves to taste success in Rockets red.
Maybe towards the end of February as the regular season winds down, can coach D'Antoni get the starters their minutes to secure the wins needed for home court advantage. At this point though, prior to the Christmas holidays, I would hope that coach Mike D'Antoni give more playing time to the bench like Tarik Black and Troy Williams, and maybe even Briante Weber. When the shots aren't falling for the shooters like Anderson, Ariza, and Gordon, he could insert Troy Williams who is very capable of scoring. In addition, giving the rest of the roster playing time will give coach D'Antoini and point guard Chris Paul an idea of the strengths of every guy on the roster and how he plays when under pressure. Just my opinion. It's really up to coach D'Antoni.
Anyone that thinks we can beat Golden State running an 8 man rotation all year is delusional. Injuries are inevitable & players will be gassed by the time we even enter the damn thing. Been like this for years.
