I'd also like to point out that I'm not yet ready to abandon an Iguodala/Young wing, nor am I ready to say that Iguodala can't play at the 2 (he has, substantially, in years past). It's all about who he's playing with, not where he's playing (with respect to the 2/3, at least).
Especially considering where Young could be in 2 years from now, which I can't say I'm ready to accurately gauge. I don't think it's out of the realm of possibility of him being a 37%+ 3 pt shooter.
What I am ready to give up on is the Miller/Iguodala/Young triumvirate. They don't fit. And I think Miller is the most replacable (partly due to age, partly due to poor fit with Young/Brand, partly because I'm not giving up on a 20 year old with Thad's potential, and partly because Iguodala would be virtually impossible to move due to his BYC status and contract. But mostly because I think he's the lesser of the 3 and has the least value).
