There has been no team that's ever come back down from 3-0 down. However, there are definitely teams that are currently attempting to do so. One of those teams is the Toronto Raptors.
After the Philadelphia 76ers took a 3-0 lead against the Toronto Raptors, many people counted them out. However, the Toronto Raptors took Game 4, and they have now forced a Game 6 by winning Game 5 in Philadelphia.
At the conclusion of Game 5, many fans took the opportunity to react to the Toronto Raptors winning, with many fans being stunned at the win. Some have pointed out that the Raptors will have a chance to complete the comeback against Doc Rivers, as he is the only coach in NBA history to blow three separate 3-1 leads.
It remains to be seen if the Raptors will in fact be able to win Game 6 against the 76ers. It's an upwards climb, but the fact that the next game is at home benefits them due to their amazing home-court advantage. Raptors fans are one of the most passionate basketball fanbases in the world, and hopefully, they can help spur the team to victory.
The Toronto Raptors have a fair amount of talent, and it is clear that the team has the tools to make things competitive against the Philadelphia 76ers. Pascal Siakam and Fred VanVleet have been All-Stars in the past, and they also have the Rookie of the Year, in Scottie Barnes. The Raptors have a lot of players that can make things difficult for Joel Embiid and James Harden with their defense.
Even if the Raptors lose Game 6, they will likely put up a fight doing so. While it is unlikely that they will be able to come back up from 3-0 down, there is a first time for everything to happen.
