You are literally saying it's no one's fault because the best player (Embiid) is out.
Simmons is a former first pick overall that can't shoot and his best asset is his defense versatility.
I like Simmons, but he has a limited offensive role for a 1st overall pick.
If the team shot well, then Simmons wasn't likely the reason. If the team team didn't shoot well, then Simmons isn't likely the reason.
Under your logic, when is it ever Simmons fault?
