Bettors who took the Miami Heat to win the Eastern Conference probably felt like they actually played a seven-game series by the time the Heat won that bet.

It took a long time and a lot of ups and downs for the Heat to finally cash the series tickets. Imagine having a six-figure win riding on the outcome.

Before the Eastern Conference finals started, a large bet came in on the Heat at BetMGM. It was a $25,000 bet at 4-to-1 odds.

Here's the roller coaster for that $25,000 bettor and everyone else who backed the Heat in the series:

The Heat won the first two games in Boston, both as big underdogs. In Game 2 they had a big rally at the end, fueled by Jimmy Butler after Celtics forward Grant Williams riled him up. Even after that start, the Heat were no lock to win the series. The Celtics were favored in Game 3. But the +400 tickets were aging very well.

•The Heat won Game 3 and everyone heard the stat repeatedly: NBA teams up 3-0 in a series were 150-0 in those series, including the Denver Nuggets in the Western Conference finals. You won't have too many 4-to-1 bets that have a 150-for-150 history.
