Embiid's injury problems are probably a mix of the flopping, trying to play as a mega wing, improper landing from all the jumping, and just plain old bad luck. It's not like the dude's flabby the way Zion was, and other current players (Jokic) and historical players (Barkley, Shaq, Yao, Heat LeBron, Wilt Chamberlain, probably Karl Malone and Dwight Howard at some point) have played in the 270+ range and been good. It's not completely impossible. Though with all of those there's caveats. Jokic doesn't jump much, which is how you accrue the most injuries. Barkley was overweight when he was playing above 255. Yao got hurt all the time, though a lot of the blame for this is on how he had to pull double duty in China. And Shaq, LeBron, Wilt, Malone and Dwight are all extreme outliers physically even among their fellow professional athletes and even here LeBron was at the lower end of things at 275ish. Shaq's also discussed how he'd been overweight and that shortened his prime, LeBron didn't stay at 275 indefinitely, and Karl Malone and Dwight Howard were technically never "officially" this heavy, so you can prune things down to literally just Wilt Chamberlain of all people. Not exactly the easiest guy to emulate.
The big issue with Embiid is that playing as a mega wing is why he's so good, but it's clearly not sustainable for him. Players heavily reliant on their athleticism are already at a greater risk for a sharp drop off when they age or get injured, just look at someone like Jeremy Lin or imagine if LeBron didn't have his playmaking and court reading skills. If Embiid plays less crazy he'll last a little longer, but he won't be able to be an MVP challenger and it seems he cares a whole lot about stuff like that. It also might just be too late at this point; he's been injury prone forever and at this point he's 30. There's a good chance that the chronic injuries ravage him even if he chills out, which would just be bad luck. He could at least stop throwing himself to the ground to sell contact and learn to land on two feet though. No harm in putting those into practice.
This highlight posted to reddit really is just emblematic of his whole career. Eye catching feat followed by instantly getting too hurt to move. Don't know how to rip reddit videos, unfortunately.
