Philly is such a dumpster fire. I can't believe there are people in this forum genuinely envious of their situation. They got nothing valuable for Noel. They will likely get nothing valuable for Okafor. Their best player has had yet another leg injury and hasn't yet showed he can actually stay healthy. They are going the be bad for a long time.
While I agree they didn't get much for Noel and likely won't get much for Okafor, they didn't do any worse than Orlando did with Oladipo who was the #2 pick in the same draft (while Noel was only #6).
Philly also has an upcoming Sacto pick that should be really good. And Embiid is amazing, though he needs to stay healthy when it counts.
While I agree with your first, I was getting more at the "over valuing" of these 2 players. They were never really that good to begin with. but I do believe they could have gotten way more for them had they basically not tanked both of their values so much, especially Noel.
As for the picks, the draft is a crap shoot and realistically speaking, Saric is probably their own regular contributor as a lotto pick (I'll get to Embiid next). He seems like he might be a solid role player off the bench. I think he's too slow to play the 3 but too small to play against regular 4s. For a small ball 4 he might be alright. But he seems to do things that might keep him in the league for like 10 years.
The issue with Embiid is and has always been his health. He's played a grand total of 33 NBA games. He missed 2 full seasons with a leg fracture and now has missed the last month and change with a torn MCL. He can be great on the floor when he plays but he'll have to actually show it it over the course of an 82 game season where he basically doesn't sit out every other night.
Simmons I can't comment on as he hasn't played a single NBA minute yet. We'll have to wait until next year to see how he looks.
