To answer the OP:
I hope so or this deal will go down as one of the worst trades in NBA history and that's not hyperbole.
The only way this goes down as the worst trades in NBA history is if the pick becomes an MVP caliber player.
I think you underestimate the risk.
If Kyrie leaves after two years and we haven't won a title the deal is a massive bust no matter who is selected in the draft. It's not just the pick, it's also Zizic (who was valued as a late lottery pick at draft time), Crowder (one of the best contracts in the league) and breaking up the core of an ascending, 53 win, ECF team. The only way that isn't true is if IT is done (and he's not).
It's also not just "the pick" but the value of the pick. There's a simple economic idea called opportunity cost. Even if the pick turns out to be a bust, there's also the question of who else could we have reasonably drafted with that pick or who we could have received in a trade for that pick. Thus Irving leaving means we gave away a good prospect, a top contract, an All-Star who wasn't yet 30 and a pick that could have returned any number of All-Star caliber players. That's an epic bust any way you slice it.
If it turns out to be #1, Bags ends up being the Next Great Thing and Irving leaves? Then this goes down as the worst trade in modern NBA history. Even worse than the Brooklyn deal that gave us those picks. It would be considered about as bad as the deal that ultimately ended up bringing Magic to the Lakers.
I'm not saying that's what it will go down as. I hope that Irving develops into what we all hope he can become and the Nets pick ends up being 7th or 8th. Then we win. But Lordy there's a lot of risk in this one.
