Btw I'm comfortable with maxing Whiteside. The deal is not without risk, but his talent is clear (put up these numbers since he started logging decent minutes), and he fits well on the team. And his skills are truly game-changing. So the main risk is that he turns into (or reverts to being?) a knucklehead.
But where else would the Heats put their money? In my mind he's clearly the best available center even over Horford and Howard. And the Heat will be stacked if Bosh comes back (and after they sign KD hehehehe)
