The foremost question on everybody's minds when Sixers president of basketball operations Bryan Colangelo and coach Brett Brown met with reporters over lunch Wednesday afternoon was simple: When is Joel Embiid going to be able to play 5-on-5?
"Right now," Brown said, "we can't give you a direct answer."
The 23-year-old Embiid, who as a rookie in 2016-17 displayed uncommon skills and equally uncommon charisma, underwent surgery to repair a torn meniscus in his left knee in March, ending his season after 31 games.
The 7-2, 280-pound center is the obvious key to a young, promising team, but he is not yet ready to go full-tilt.

"If you walk in the gym, it looks like he could play 5-on-5 basketball," Colangelo said. "But we're going to take our cues from the people who know best."
And right now the Sixers' medical staff, headed by the newly hired vice president of athlete care, Dr. Daniel Medina, favors what Colangelo called "a hyper-conservative progression."
"Will he be ramping that up throughout the preseason?" Colangelo said "Yes. How many games, we're not certain. Is it every game? We don't know. That will be based on what we're told."
The Sixers open training camp next Tuesday in their Camden, New Jersey-based facility. The preseason begins Oct. 4 against Memphis at the Wells Fargo Center, while the regular season opens Oct. 18 in Washington.
"It's not about being ready for the first practice or the first game," Colangelo said. "And he will be out there for the first practice and the first game. The question is how much, how little, if at all. Those things will be determined by certain criteria along the way."
Colangelo said, in fact, that he has a document that spells out the criteria that must be met before Embiid can play.
"There is a plan in place," Colangelo said, "and it's a progression-based plan. It's criteria-based, and as he's checking off boxes, and continues to jump over each and every successive item, then we'll put him out there on the floor. There's no timetable. There's no scheduled number of minutes. There is no decision on back-to-backs. All of that is yet to be determined."
Embiid, the third overall pick in the 2014 draft, missed his first two seasons while recovering from a broken foot. He averaged 20.2 points, 7.8 rebounds and 2.5 blocks last season, despite a minutes restriction; he averaged just 25.4 a game.
When Brown was asked whether Embiid will be on such a restriction this season, he said, "We all hope not, obviously."
The other question about Embiid concerns whether he and the team can reach an accord on a contract extension. Colangelo said he is "cautiously optimistic" that that can happen before Oct. 16, the NBA's deadline for extending players on their rookie deals.
But the primary question remains about Embiid's health.
"This really is about creating an opportunity for him to have long-term, sustainable health," Colangelo said, "not to get ready for the first preseason game per se, or the second preseason game. Again, that progression is going to lead to hopefully a full season of competitive basketball, without restriction. That's the goal."
