No, Billups was their go-to guy.
Players listings are usually outdated. You think R. Wallace or K. Thomas still weigh 230 and 235? Not a chance. But that's what they're still listed at.
I'll give you an example...

"Popovich said Duncan has lost 15 pounds and now weighs 240"
Yet if you look on any site, you'll find he's still listed at 260.
I also heard last season that Bynum is 272 (still listed at 285), Nowitzki is 243 (still listed at 245), Bosh is 245 (still listed at 230), etc.
I can't remember where I read or heard it, but I remember reading or hearing that Noah weighs 260 (I knew full well he was still listed at 232, though). Why would I lie about something like that?
