While it's easy to defend the Miami Heat for not having a full season together, their preseason shenanigans made one thing very clear: It was championship or bust.
After losing to the Dallas Mavericks in a flaccid effort after the third quarter of Game 2, it was a disappointing bust.
But can that be sports' biggest disappointment? Teams and players can let down their fanbases for all sorts of reasons: expectations not met, injuries randomly incurred, scandals unearthed and just general injustice.
LeBron James said he wanted "not two, not three, not four" titles...and if he's history's biggest letdown, he'll be on his way to one.
