Giddey is 19. I understand that a bunch of 1sts is also in play here, but the last 7 1sts we had resulted in one quality starter but not a star (Robert Williams) and one marginal rotation player (Grant Williams). The others are either gone or only play episodically.
Giddey may end up being a great player but that's going back to square one, even if it works.
If you want to get a player, my guess is that Brown or Tatum will net you Dejounte Murray plus additional assets. Obviously Tatum would mean a bigger additional haul. If we were blowing this up, I'd rather offer Tatum for Murray, Keldon Johnson and next year's unprotected 1st from SA. I would guess they'd do it, and I think we'd be better off. I'm less impressed with Tatum than most, and think Brown still has upside as a scoring machine, especially with a real point and no Tatum.
