These trades won't happen until draft night so not sure you can climb the latter like that.
Also, Hornets will get better offers than that... Boston has been said to want to move there. I'd be willing to do 12 plus the OKC pick or our pick next year top 5 protected to get to 9 if Johnson, Hezonja, or Porz are there (WCS may fall and I don't think I'd move up for him). I think one of Porz, Hezonja, or WCS slips a bit on draft night just the way the teams are lined up. I think Detroit will take Johnson if Mario and Winslow are off the board.
Rumor has it that 8 is available... SVG mentioned he needs a backup center and a SF... wonder what we could cobble together.
Jazz would have to overpay for 9 in advance and see if the second leg materializes once the draft begins.
12 + Hood might get the Jazz to 8, but that's a tough decision if you like Hood.
Would be better to try for 9.
