One of the biggest question marks moving forward when it comes to the Sixers is the health of their two stars; Joel Embiid and Ben Simmons.

The duo has appeared in just 31 games combined in four NBA seasons.

Hopefully that's about to change.

When speaking on Friday during a press conference, Sixers President of Basketball Operations Bryan Colangelo addressed the biggest elephant in the Sixers room - health.

"I think both Ben and Joel are on course for recovery," Colangelo said when asked about his plan regarding the minute restrictions on Embiid, Simmons.

"I’d throw Robert Covington into that mix too, who’s overcoming a surgery that I believe was in May. But the bottom line is that we anticipate a full, healthy roster and we’re going to Summer League to try to look and see how the young players are developing and what their health statuses are. But yes, we look to have a full roster, and once again, if the health and medical performance staff tells us that we’re ready to go, then we’ll go."

The biggest question that needs answering is Embiid.

The 7-foot-2 big man is the difference-maker.  Last season he flashed brilliance over his 31 games, putting up historic splits while playing on a minute restriction and sitting out the back-end of back-to-back games.  The one thing that seemingly can hold him back from being a franchise altering player is his health.  Embiid missed his first two NBA seasons after multiple foot surgeries and sat out most of last season when it was revealed he needed surgery to repair a torn left meniscus back on March 24th.

Last season, Embiid did not play in back-to-back games, something that hasn't been discussed yet entering this season.

"There really hasn’t been," Colangelo said when asked if there have been any discussions about not playing Embiid in back-to-back games.

"But he’s a unique individual in a lot of ways: size, strength, power. He plays with reckless abandon and some of that has got to be controlled. At some stage, guys fatigue and they need to come out and there will be times when players need rest. But we’ll let the medical staff and our performance staff try to guide us on those decisions. We want to maintain and sustain their health for a long career, not just that particular game."

Embiid averaged 20.2 points, 7.8 rebounds and 2.5 blocks during his rookie campaign in just 25.4 minutes per night.

Then there's Simmons. The 6-foot-10 former No. 1 overall pick has never stepped on a NBA floor.  While he was cleared back in April, he won't play in the Summer League, but from the looks of the video below, he looks like he is doing just fine.

Like many conversations when talking about the Sixers "if" Embiid and Simmons can remain healthy, with the addition of Markelle Fultz, this season should be at the very least an entertaining one.
