Last season, the Sixers went 0-26 when trailing by double digits entering the 4th quarter. This season, they are already 3-0:
Down 11 entering the 4th vs. Celtics = Win
Down 10 entering the 4th vs. Hornets = Win
Down 16 entering the 4th vs. Wizards = Win
It's the most such comebacks through the first four games of a season in NBA history.
Here's an idea
Don't go down by double digits entering the 4th
Also two of those teams are absolute dogshit and one is missing their second best player
