Doubt they would trade Hollis-Jefferson in any scenario, he's the only guy they have anywhere near the "young talent" category.
The guy who intrigues me there is Thad Young. Good contract, good age. And actually fits the need for a stretch(y) combo forward. Not sure what the Cavs could offer, though I guess Mozgov might intrigue Prokhorov. They'd definitely want a pick, or several of them. Plus the Cavs don't really have up-and-coming youngsters to peddle, maybe save for Cunningham and the rights to Cedi Osman.
Also, Young doesn't quite fit into the Haywood TPE and it gets really tricky from there unless i'm misunderstanding some of the rules.
Worse, it would need to be two separate trades and they don't really have a contract that would match Mozgov's. So that means a combination of Bogdanovic and one of Larkin, Ellington, Karasev or Bargnani. But now we're at 3 players coming in, so that means at least two need to go out...
Anyway, just too difficult probably, unless a third team is involved. And why would anyone get involved in that, save for some sort of a Bogdanovic fetish.
