Fun fact: the Celtics have given up the biggest comeback in the NBA this year (Hawks) and last year (Nets).
It's definitely not a coincidence, but I'm also not sure how predictive it will be regarding our playoff chances.
On the optimistic side, these comebacks seems to happen against lesser competition. My only playoff concern (regarding blown leads) is maybe a first round opponent steals 1-2 games with the C's not taking them seriously (like vs Hawks last year), or maybe if a later opponent is down a superstar (like last year when Embiid or Dejounte Murray missed a game in their respective series).
The Hawks were 31-39 and missing Trae Young.
Last year the 28 point blown lead against the Nets, that was a team who had traded away their 2 superstars (Durant, Irving) and were 7-15 since Durant last played a game for them.
Earlier this month, the 22 point blown lead against the Cavs, Mitchell was out and Mobley went out with an injury before the Cavs made their comeback.
Earlier in the season, the 18 point blown lead against the Hornets, they were 3-9 and missing Rozier.
This is partly why I want to get Miami in the first round, I think the C's are more likely to take them seriously throughout and not give away any games.
