“Celtics on the Verge of History: Can they make a historic comeback against the Heat?”

Maybe Kevin Garnett was right. Perhaps, as he yelled to celebrate Boston’s 2008 championship, anything really is possible.

Even the impossible.

The Celtics are close to making history and with that they would enter a select club.

Of the 150 teams that have trailed 3-0 in a seven-game series, only 14—9.3%—found a way to extend to Game 6. None have won the series and most were out in this point.

But it hasn’t been like that with the Celtics. They cut the deficit in the Eastern Conference finals against the Miami Heat to 3-2 and although they are down in the series they maintain the momentum heading into Game 6 on Saturday in Miami.

“Obviously we didn’t imagine being in this position, down 3-0, but when adversity hits you can see what the team is made of,” admitted Celtics forward Jaylen Brown. “I mean, it couldn’t be worse than being down 3 -0, but we didn’t go in opposite directions, we stayed together”.

Only three teams have tied the series 3-3 after being down 3-0; the Celtics could become the fourth team with a win on Saturday. Neither team has escaped the 3-0 hole, but a victory in Game 6 would give Boston a chance to make history in Game 7 — Monday at home.

“One of our assistants put it in perspective: The season is nine months and we just had one bad week,” Celtics coach Joe Mazzulla said.

While the Denver Nuggets wait for their rival. If Boston wins the series, the Nuggets will visit the Celtics for Game 1 of the NBA Finals. If Miami wins the East, the Heat will travel to Denver for Game 1. Either way, the championship series starts on June 1, somewhere.

The Heat led by nine points in the third quarter of Game 4 and were in position to win with a sweep. But in two and a half minutes they let go of the lead and the Celtics haven’t trailed again.

“The last two duels are not who we really are. It was like that,” acknowledged Heat forward Jimmy Butler. “We stopped playing defense in the middle because we didn’t make the shots we wanted to hit. But that is easily fixed.”

At least his confidence hasn’t shaken.
