I think I'd still prefer Howard, Battier, or Prince; however, I'm not sure how realistic any of them are. Howard has contract complications, I don't think the Rockets want to trade (or at least give away) Battier, and Prince makes too much money not to include more assets.
So if we can't get a top wing anyway, I'd be willing to roll the dice on Shaq and Moon/Parker. We'd get a pretty good wing and we'd get post scoring and insurance.
And then if Perk miraculously does come back, we could consider trading one of our bigs near the deadline if we really feel we need an upgrade at the 2/3 spot.
