Again, what is he good at?
Drafting? (probably not)
Trading? (seems decent)
Establishing relationships? (definitely not)
Recognizing that super-tanking could be a lucrative strategy for a team with no assets is not hard. The only thing that distinguishes Hinkie from other GMs (other than his savant-ish ticks) is that he had the guts to actually try. He was fired for his troubles.
Who caresabout establishing relationships? Everybody like Billy King... How'd that go?
Hinkie literally has never lost a trade. He's pretty much either won outright, or it has been mutually beneficial. He's a phenomenal trader, and probably an average drafter.
What trades has Hinkie won outright?
The only thing I notice is the MCW trade.
The only other major trade I see is the Jrue Holiday/Nerlens Noel trade, as of now I'd say it's a wash considering the number of games both Noel and Holiday have played (though what happens to Noel in the future could tip the scales one way or the other). The other part of that trade was getting Elfrid Payton (who they traded for Saric). The jury's really still out here (and will be for a couple of more years as Noel, Payton, Saric establish themselves). To me that's hard to call it anything but a wash, at the most it's a slight win.
Everything else seems barely significant to me. Unless you value acquiring 2nd round picks, he pretty much just traded scraps for scraps, or expiring contracts for scraps.
Though he did acquire a couple of late firsts and a pick swap (which is unlikely to materialize) in salary dumps, not bad. Those are definitely good moves for a GM without much else to work with.
But still, it looks to me like he won one trade outright.
To be fair, I don't think he was around long enough or had enough assets to really establish himself one way or the other. Had he had maybe another year or two to let him try to fill the roster around Embiid/Simmons and flip the other pieces, it would have been interesting to see what he could have done.
I find it really hard to call Hinkie a phenomenal trader though with what he actually did.
