This is pretty straightforward. Markkanen is a prime star, PG13 is a declining HOFer, he's not washed up but his not close to a star.
76ers:
If Embid has 1-2 years in him they have to pair him with a good players, if this doesn't work out most likely Markkanen will still retain most of his value to be traded later on (I'm sure the pistons will go for him sooner rather than later).
Jazz:
3 picks from a declining team is all they can hope for. Wait too long and an injury or something might hurt their chances to get value from him.
