I still like Simmons, more than I like say Lonzo Ball, but he does not have franchise player level value right now coming off that post season.
What do you mean by franchise player value?
If you mean:
(a) his current performance levels are not equivalent to a franchise player, I agree with you.
(b) his current trade value is not good enough to get a franchise player who is not forcing his way / or his team is in fear of him forcing his way out in the near future, I agree with you.
but
(c) his current trade value is not good enough to get a franchise talent who is forcing his way out or his team is in fear of him leaving in the near future, then I disagree.
I believe Ben Simmons is plenty valuable enough to net a franchise player in that scenario. He has a tantalizing array of size, athleticism and skills plus there is reason to believe he could do better without Embiid clogging the paint whereby Ben could better utilize his talents.
That is a very good return for a team who has little to no leverage and is losing their star regardless. A very competitive offer.
