When a workforce takes a three-games-to-none lead in a best-of-seven collection, it’s time to begin waiting for the subsequent spherical or to a championship parade.

Most of the time.

In the historical past of sports activities, a number of groups with 3-0 collection leads have managed to lose three straight video games earlier than recovering. Some of them misplaced another sport — and the collection — as effectively.

That’s the historical past dealing with the Miami Heat, who gained the primary three video games of their N.B.A. Eastern Conference finals collection in opposition to the Boston Celtics, then misplaced the subsequent three, together with Game 6 at residence on Saturday evening.

Game 7 is Monday evening in Boston, and the Heat are 48 minutes away from historic ignominy. No N.B.A. workforce has ever blown a 3-0 collection lead courting to 1947, when the N.B.A. was referred to as the Basketball Association of America and had groups just like the Cleveland Rebels and the St. Louis Bombers. This yr, within the Western Conference finals, the Denver Nuggets took a 3-0 collection lead in opposition to the Los Angeles Lakers, then completed them off in a four-game sweep.

A collapse after taking a 3-0 collection lead has occurred in different leagues, although. Let’s relive a few of these darkish moments (for one workforce in these collection anyway).

Baseball

The most well-known 3-0 comeback in sports activities actually got here in 2004 when the Boston Red Sox stunned their hated rivals, the Yankees, and made Major League Baseball historical past.

The victory within the American League Championship Series, snatched from the jaws of defeat, got here in defiance of the fabled Curse of the Bambino that had supposedly consigned the Red Sox to perpetual defeat after they offered Babe Ruth to the Yankees in 1920.

“This is obviously crushing for us,” mentioned Yankees third baseman Alex Rodriguez, a sentiment the Heat might quickly be feeling.

The solely different time a serious league workforce battled again from 3-0 down, it didn’t end the job. The Tampa Bay Rays raced to a 3-0 collection lead within the 2020 A.L.C.S., performed at a impartial website in San Diego due to the coronavirus pandemic. The Houston Astros claimed the subsequent three video games, however Tampa Bay pulled out a 4-2 victory within the decider earlier than dropping the World Series to the Los Angeles Dodgers.

“I don’t know if I went to bed,” Rays Manager Kevin Cash mentioned in regards to the aftermath of Game 6. “It was tough, there’s no doubt. A lot of anxiety.”

No workforce has blown a 3-0 collection lead within the World Series, however within the Japan Series, the Nishitetsu Lions got here again from 3-0 right down to win in 1958 in opposition to the Yomiuri Giants and the Giants managed the identical feat in opposition to the Kintetsu Buffaloes in 1989.

Hockey

The N.H.L. has handled followers to probably the most four-game collapses, and a type of got here within the Stanley Cup remaining.

In 1942, the Detroit Red Wings gained the primary three video games, however the Toronto Maple Leafs came roaring back with four straight. The Cup had switched to a best-of-seven format in 1939 and this was the primary collection to go the gap.

“By Jiminy” was the postgame response of the Leafs nice Syl Apps.

Four-game comebacks had been additionally achieved in earlier rounds by the Islanders over the Pittsburgh Penguins in 1975, the Philadelphia Flyers over the Boston Bruins in 2010 and the Los Angeles Kings over the San Jose Sharks in 2014.

Basketball

Although no N.B.A. workforce has — but — misplaced a collection it led by 3-0, a number of, like this yr’s Heat, have misplaced three straight to get to 3-3.

It occurred as soon as within the finals, in 1951. The Rochester Royals (now the Sacramento Kings by way of Cincinnati, Kansas City, Mo., and Omaha) took a 3-0 lead over the Knicks, who rallied with three wins. The remaining sport got here right down to the final seconds earlier than Bob Davies of the Royals sealed it with two free throws.

It is the one and solely championship for the Royals/Kings franchise, in any metropolis. The Knicks must wait till 1970 for his or her first.

A 3-game collapse adopted by Game 7 redemption was additionally achieved in earlier rounds by the 1994 Utah Jazz in opposition to the Denver Nuggets and the 2003 Dallas Mavericks in opposition to the Portland Trail Blazers.

So the total collapse has by no means occurred within the N.B.A. But in all of basketball?

How might you neglect the basic Beermen-Aces collection?

In the 2016 Philippine Cup remaining, the Alaska Aces seemed set to assert the title after three straight wins. (Their identify got here from their sponsor, Alaska Milk, not their residence base.)

But it was a mistake to rely out the reigning champion San Miguel Beermen, who gained 4 straight to do what no N.B.A. workforce has ever completed.

The Celtics will likely be hoping to match the Beermen on Monday evening.
