I don't believe the rumors. Athletic, young 7 footers with his pedigree (his mother was a great player) don't grow on trees. He's a project, but so is Thrabeet, and McGee costs less than half of what a #3 pick costs. If anything, thae rumored deal would be a salary dump by OK City.
And if the #3 pick is being shopped, I'd certainly be willing to buy it to get Rubio (but not Thrabeet).
