I think The Process Era in Philly has run its course.
Embiid has lost interest in not only the organization but the fans and the city as well. I know people are going to say he's just rusty and give him some time, but you can see in his eyes and body language that he's checked out.
Maxey now wants out, so I doubt it's because he wants to be the focal point but probably just wants a new start somewhere else, tired of the dysfunctional atmosphere in Philly. That McCain kid is nice, but giving him the keys this early, it's hard to say if his play is truly sustainable long-term; in other words, is this just a fluke run for him, or is he really legit?
On paper, this Sixer team looked good, probably the best team they've had on paper since the Jimmy Butler era, but unfortunately, some things are deceiving as it's proven most of their roster is either washed with old or injury-prone players or just unplayable.
Despite Joel's flaws in terms of his injuries, there are plenty of teams that would still take him but the problem is that I think if he were traded it needs to be with a contender so that it puts less mileage on him, basically reducing him to being a second or third option so that you can maintain his health, Philly has run him into the ground and that's why he's become very injury prone these past few years.
