If lebron is so qreat why the spurs crushed him bad?

It's because Lebron had a weak supporting cast. Ben Wallace, Wally, Gibson, Big Z, and Anderson Varajao which is horrible no Mo Williams or Jamison. And Spurs were far more dominant with Parker, Ginobili, Duncan, Finlay, and Bowen these players were all healthy. I have no idea how the pistons would even lose to suck a weak team like the cavs i mean seriously they choked.
