What trade value do you see the other guys as having? Assuming there isn't a lockout, who wants to pay Frye and/or Warrick what we're paying them?
We're so good at saying "trade everybody!" but most of the time people don't understand that it takes two to tango. Right now, I'll be happy if only Carter is moved, he's dead weight right now. But he's also an expiring. An expiring benefits us just as much as it does another team, which is why the front office won't be too sad if they aren't able to trade him. Who even knows how much effort they are putting in to actually trade him anyway?
Childress would be a good trade asset, but since he gets no time, we're stuck with him. He even makes too much money to use as a throw-in.
You know as well as I do, there is almost always someone out there willing to take a shot at a player because they think you are using him wrong or because they think they can coach better. There are teams willing to take a bullet to get a 3 way trade made or because they want to make a deal work.
What is the alternative? Let these guys play out their contracts and continue the Suns futility in getting a title?
That's not the answer either.
The team is going to have to do a combination of trading and drafting to retool this franchise. Sitting on their hands with this roster and signing aging vets and mid tier players isn't going to get it done. The end game is a title. It's not being just good enough to make the playoffs.
