The Boston Celtics face a large deficit in their Eastern Conference Finals series against the Miami Heat, but it's not an insurmountable one.
The Heat took a commanding 3-1 series lead with a 112-109 Game 4 win over the Celtics on Wednesday night.
NBA teams that jump out to a 3-1 advantage win their series 94.9 percent (244-13) of the time. The percentage is almost the same in the conference finals.
We've actually seen a 3-1 deficit overcome twice in the 2020 NBA playoffs. The Denver Nuggets battled back and beat the Utah Jazz in the first round and the Los Angeles Clippers in the conference semifinals despite being down 3-1 in both series.
The Celtics have done it twice, too, with the most recent instance coming in 1981 en route to Larry Bird's first of three championships with Boston.
If the Celtics are going to reach the NBA Finals, they'll need to join these teams that have overcome a 3-1 deficit in a best-of-seven playoff series.
