I think nearly everyone is on board with the idea, I just don't see why he comes here. It only makes sense to bring him here if you want to try to compete for a title. To do that, we definitely need KG back and we need some, if not all, of Jeff Green, Brandon Bass, Mikael Pietrus, and Ray Allen. If we want to bring at least some of them back, we're not going to be able to offer Duncan an exorbitant amount of money.
If we aren't going to offer him a ton of money what's really the allure of coming here? San Antonio is still very good, so it's not like he's playing in a bad place. And if he really wanted to jump ship to a better team, why not just go to OKC or Miami?
So, if Danny could somehow swing it, I'd love it. Bringing everyone back and adding Duncan could lead to a title. But I don't see it happening.
