Ben Simmons is out for the Sixers' seeding game Friday against the Orlando Magic with a left patella subluxation and there's not currently a timeline for his return as he considers treatment options. That news is clearly significant in the Sixers' world, and it raises a range of questions.
Let's run through some of the bigger ones:
What exactly is the injury?
A simpler way to classify the injury is as a partial dislocation of the kneecap.
How long will Simmons be out?
This is the largest question and still murky. Brett Brown on Thursday said "stuff is still being evaluated" and that he wasn't in a position to offer a timeline. Presumably, factors such as the state of the ligaments around the knee could play a key role in determining how long Simmons is out.
Outside of Simmons' physical status, the team's approach will be important. There's no reason to put Simmons back on the court before he's healthy.
Shake Milton is hoping for a speedy return.
"It's tough for us," he said Thursday. "Ben is an incredible player, an incredible athlete. I don't know, he's like a freaking superhuman, so hopefully he's able to heal super fast and get back on the court, because we definitely need him."
How will the starting lineup change?
On March 11, the Sixers' final pre-hiatus game, the team started Milton, Josh Richardson, Tobias Harris, Al Horford and Joel Embiid. That's one possibility. The Horford-Embiid pairing is still the Sixers' worst regular duo in terms of net rating despite having a plus-15.6 net rating in 40 minutes together at Disney World.
If Brown wants to prepare for a scenario in which Simmons is available and in the postseason starting five, he could keep Horford as the sixth man. He could instead turn to a wing such as Matisse Thybulle, Furkan Korkmaz or Glenn Robinson III, all of whom have started games for the Sixers this year. Robinson, who has missed the Sixers' first three seeding games with a left hip pointer, is doubtful for Friday's game.
What about the rotation?
Robinson's health is a relevant issue with the rotation, which Brown shrunk to nine players when the Sixers played the Wizards. Raul Neto didn't play against Washington after seeing time in the first two seeding games.
It's interesting to note that Neto started in Simmons' place on Nov. 8 and Nov. 10 when the Australian was out with a shoulder injury. The circumstances were very different, however, as Milton was sidelined by a bone bruise and left knee sprain, leaving Neto and Trey Burke as the two main ball handlers on the roster. Trade deadline acquisition Alec Burks now appears ahead of Neto in the backup point guard pecking order, and Simmons' injury should increase Burks' value a touch.
As of Wednesday, Brown said his plan was still to have a nine-player rotation for the playoffs.
What's the intangible impact?
When Simmons suffered a nerve impingement in his lower back on Feb. 22, Brown recalled him vomiting because of pain. He's lauded Simmons often for the diligent rehabilitation he did to recover from that injury and be ready to go when play resumed amid a pandemic.
Injuries aren't anything new to Brown, but he admitted it hurt some to learn about this one after witnessing the process of Simmons' back rehabilitation.
"It's the life that we've lived since I have been in Philadelphia," he said. "I'm sure every coach has some level of a similar story. This one stings, for sure. We all felt with the pandemic and are we going to play again, it obviously bought time for Ben - had the season kept going, it's anybody's best guess. In relation to being incredibly down about it, I'm not. When I think too long about it, probably I can go there.
"But I feel numb to it. I feel conditioned, that we've gone through this type of thing before. There is a level of faith that I have in the rest of the team that we can hold the fort until we hopefully get him back. But snakebitten, woe is me, I don't go there."
In addition to dealing with the disappointment of a star going down, the Sixers will have to tinker with ingredients like leadership that aren't necessarily evident to an outsider.
"It's going to be kind of everyone has to step up by committee," Richardson said. "I think we have a few guys that can step up as leaders, who can step up and have big games for us. We don't really like to put too much pressure on one or a few guys. Everybody's going to step up in his absence."
Can the Sixers manage without Simmons?
Again, the lack of a timeline looms large here. We can say without question that the Sixers are 6-5 this season without Simmons and don't have direct replacements for his elite defense, transition talents, creative passing and more.
It's also logical that the Sixers will rely on Embiid defensively and feed him frequently in the post. His 34.4 percent usage rate so far in Florida may very well rise.
"Offensively, he needs to get as many touches as we can get him," Brown said. "And I think that one of the areas of most noticeable growth … is what he's been doing passing out of the post. It's maybe the single thing that stands out most to me offensively when you look at whether it's Jo, or just us as a team - I like our post spacing.
"I like Jo's unselfishness quarterbacking the gym. His ability to read where the double teams are coming from I think has been shown."
Thybulle, Richardson, and perhaps Robinson when healthy could assume challenging defensive assignments that otherwise would have been Simmons'. Players like Harris and Korkmaz will miss Simmons' ability to drive and set up three-pointers.
Initially, the Sixers are coming to terms with the situation and hoping the injury doesn't dent their playoff hopes.
"There's a lot of moving parts right now and really we're all coming to grips with the news that we've received," Brown said.
