IMO, building around Embiid is a risky proposition. He's already missed 14 games this year, missed ~20 games in his 2 "healthy" years, and missed most of the 3 years before that (and all of the Big 12 and NCAA tourneys while at Kansas).
Last year in the playoffs, he had to have treatments every day in order to be able to play. 7 footers with bad feet or knees are just a bad gamble. lol at posters who act like this isn't a massive issue facing the 76ers.
I think Simmons' game is too flawed for him to be a #1 guy. But IMO, he's the one Philly has to keep. If I were them, I'd be looking to move Embiid. We're fortunate that the 6ers had the guy they really needed on their roster and let him slip away last offseason. Now they've got a bloated roster with bad contracts that isn't very good past the starting 5.
