The fact that they are in the East means they will coast to the ECF
But if the ECF is a war with Indiana and they somehow beat them, they aren't winning in the NBA Finals. Whoever comes out of the West will be more ready and probably playing their basketball due to how much competitive that conference is. Hell, SA was a rebound away.
Boston also was up on them 3-2 two years ago and LeBron had to have 45 to push it to 7. If MIA gets down in a series again 3-2 or w/e, they aren't winning it this time around.
