Trading either would have to be a win-now move, which means Sully is the one to go, being less able to contribute in the Finals this year.
But I'm not sure I want to bother to give up anything on the roster in trade to simply return another journeyman. Maybe Melo, but I'm keeping Joseph even. It's just not worth the trouble to reshuffle the chairs.
But if it comes down to trading up for a current allstart talent (or nearly so), I'd have to say do what it takes. But I'm so high on both that I think I'd have a hard time letting both go for anything but a star or allstar.
Bradley, Sullinger, Joseph, Pick is one heck of a start to a package, especially when they can be matched with two journeymen starters, a guard (Lee) and forward (Bass). Add it up, and it's a nice deal to a rebuilding team:
Lee+Bass=$11M+Bradley+Sullinger=$15M-$16M for an allstar?
Need to add a couple of min contracts or take back 2nd rounders or something cheap to stay under the cap, but that's a rotation that coule make it with, oh, say, Josh Smith extended?
Enough chips to cash in, enough horses to win with that rotation+Smith?
I say trade all or none!
