It's not essential to play that position. You do need some handles. Rahk wasn't a good PnR guy this past year and yet he played a vast majority of the minutes there. You need at least one guy to be able to run the PnR on the floor. You don't absolutely need two.
I definitely could with another year of development. And Tyson isn't going to excel in that area either. So why would we take him over Hunter even if Iggy dropped first? That's just how I'd do it.
And we all know JB has changed his offense several times here. I'm confident he could find a way to make it work. The common thing we've had his entire tenure is shooting. And all our remaining targets have that. I'd take the higher upside guys, personally.
