Luwawu I guess would have the defensive edge, but Korkmaz has the better shooting for sure and in today's NBA that's pretty important... you only have to look at the successes of Booker, McCollum and Hood to realise that...
So yes I guess if you're swinging for the fences then Korkmaz, but I guess Luwawu's appeal is his more well rounded game.
I'm not sure. I think Luwawu is a straight-line driver and spot-up shooter. Yes, I think he can defend, and I think he'll be a decent player, but I don't think he gives the Jazz a new dimension. Korkmaz gives the Jazz pretty elite shooting and passing, plus the ability to switch defensively, since he's 6'7". Pretty ideal if you ask me.
