great trade for all sides, IMO.
Wolves got a ton of value from a guy who was 100% guaranteed going to walk away. Cavs obviously got an allstar. And the sixers...well, i'll go into a little more detail on why i like it.
Thad Young was quite unhappy last year and so maybe this is them doing him a solid (since the Wolves will be an exciting team next year). Additionally, getting a mentor for Embiid (yes, i believe the reason) is a great move. I am in the camp that believes young teams absolutely need vets to teach them about off-court stuff, which usually translates into good on-court habits.
The Sixers are getting a lot of flak but essentially, what they're doing is still securing assets. But instead of acquiring a treasure trove of mid-tier draft picks, they're making sure their own picks are gold. And for all this talk about "they're going to need to pay those kids some day", "they have too many high upside guys", etc. etc. Well, you saw what happened with Love. Some team is going to give up proven talent for upside. You see it even on these forums, with all these trade Rondo for <young guy> ideas. It's not unreasonable to think that at some point in the next 2 years, the Sixers could likely package MCW+Embiid for a perennial all-star, and the #2 overall pick in 2016 for another all-star.
