The KAT situation is interesting. If he indeed is trying to push his way out, the Suns have to be in on the discussion, but otherwise they might just consider staying with what they have.
Yes, Tyler, Frank, and Saric are moveable for the right piece--a pf who can block a few shots and score. Maybe Pop decides to get some value for Alderidge. He would be a better fit than Love.
Tyler, Frank, and Saric plus a pick or two might get it done. Frank and Saric are both young pieces that Pop seems to work magic with. Tyler also seems like a SA type of player, but he would free up a lot of cap space for them, and they get picks to rebuild with. I am intrigued by Alderidge but not that excited about him. So I would not be willing to give up more.
