1) Why would the Wolves want David Lee? That's 3 starting caliber PF (along with Love and Jefferson). They need backcourt depth or a Center. Not another PF.
2) I'm pretty sure the NBA is a little bit bigger than Rubio and Joventut. If he didn't want to play for the Wolves he should have A. not put his name in the draft or B. waited until his contract with Joventut ran out. He needs to grow up and realize that he's in a position that millions of people would kill for.
You don't see Steph Curry acting like a little bitch because the Knicks didn't get him.
