Embiid is awesome, but when Seth Curry is your 2nd leading scorer it isn't a surprise that you lose a 7 game series.
As I've been saying for awhile, Simmons isn't the biggest Sixers problem, Harris is. So if they trade Simmons, they need someone that is an upgrade on Harris as the #2 option. That to me is the problem with the Sacramento trade that was proposed. Hield, Haliburton, and 9 doesn't upgrade Harris as none of those guys are good enough as a 2nd scorer to really fix Philly's biggest problem.
