The reality is, based on Embiid's history and the Sixers history, to say nothing about the questions surrounding Harden, there is no "next season where they have a better chance" to save him for.
Maybe there will be, maybe there won't be, but for now trying to even this series is all anyone can count on.
Still not clear if he actually had a concussion or just had to clear protocol because of the nature of the injury and symptoms. Perhaps there's no difference (but still considered minor or he wouldn't have been able to clear).
Anyway, there's no baseball on, so...
