It's time for the NBA's fight of the year.

After spending a whole season talking about Indiana and Miami squaring off in the Eastern Conference finals, the long-anticipated rematch begins Sunday when the top-seeded Pacers face the two-time defending NBA champion Heat in Game 1 of this best-of-seven series.

Miami has won the last two playoff bouts — winning three straight to oust the Pacers 4-2 in the second round in 2012 before blowing out the Pacers in Game 7 last year in the conference finals.

This year, the Pacers made it clear from the start they wanted the No. 1 seed to assure Miami had to play in Indy if there was a Game 7.

All they have to do now is prove they can beat the champs.
