Obviously because not everyone considers him the "next big thing". Opinion is mixed on the guy. Already having Johnny Flynn (who should have a long and productive NBA career at PG), I would have no hesitation at all to trade Rubio if I were the T-Wolves. It looks like they have the same idea. Now it's just a matter of getting the best deal possible. The team that gives up a lot for him may end up with Fool's Gold on their hands.
That's debatable. Kevin Love's rookie year already matches David Lee's career average with fewer minutes.
I believe it's bound by the rules that there's a certain limit to those endorsement dollars Minny could offer. Someone corrects me please if i am wrong.
