I'm not a Miami fan, but yes, I hope that they start playing better for my NBA watching's sake. Watching the Heat grind one out over the Wizards or Nets isn't especially interesting to me.
BTW, I think this picture can sum up the rather stupid hatred of Lebron as any.
I think everyone agrees that Lebron made a poor choice in how he announced his move to Miami, but he doesn't need to be vilified to the extent that he has for going to another team. It's a little ridiculous.
