It's amazing the snowball effect of Brad not including Hugo and Baylor for Giannis has had on the NBA off-season. With Giannis, the Celtics would have been legit title contenders. And both Philly and Miami would have been closer to play-in status.
Let's also not forget ramifications of the playoff disaster. If the Celtics beat Philly, do the 76ers have the same off-season? Sure, the Celtics still may have traded Jaylen, but would Philly have bothered making the offer?
As for LeBron, he will definitely be a big help for Philly. That team will be fun to watch and should unfortunately be the favorites. However, as with every season for them, Embiid's health is the biggest factor.
