The bottom line for me is I do not see the current foursome of Embiid, Simmons, Harris and Butler with a limited bench and no cap space as being good enough to win a ring.
Embiid and the 76ers need to figure out how to condition/manage his body better and Brand needs to find a much better backup C.
Simmons needs to learn and be willing to take jump shots (and foul shots) and stay aggressive at all times. Other than Butler, we need better G depth too with TJ likely gone and JJ uncertain.
Harris and the 76ers need to find ways to expand his skill set to include improved rebounding & defense. Those are key elements to a winning team; we need much better rebounding throughout the roster and a focus on defense.
The turnover mgmt, rebounding, defense and shooting consistency areas all need attention in constructing the roster. Players need to be versatile, dedicated to their craft and team first in their approach. The organization and coaches need to reinforce this relentlessly with words and actions. Accountability needs to be #1 for everyone.
