If Exum is the player available, at 4 or 5 from the Jazz, and we have Parker then I do it. However, I wouldn't if it's for Randle.
Kanter and rights to Exum for rights to Parker works for me. Kanter fills a major need at C, is still only 21 (22 next month), and has shown improvement each year. I obviously would love to get a future pick, but I would be happy with that trade.
