You have to do it if you're Utah. Brand at 3 is better than Boozer at 6. We will not get a better offer for AK.
That deal comes with a MASS amount of trepidation about Brand. I don't remember him being smooth enough athletically to run the pick and roll well. And he's no center either, much in the way Boozer was, so getting Favors along with it means there are three PF on the roster. That won't help against the Lakers.
And I have trouble thinking that Philadelphia gives up the 2 for two years of financial relief.
