They are favoring this trade in Pistons forums? That's awesome. I agree with those that say it would basically be Sully and the #16 for WCS, but if for some reason he's taken, then Hezonja, Winslow, or Porzingis would be the consolation prize - still totally worth it. Remember, we have two glaring needs and one of those is an athletic, scoring wing.
If we did end up with Winslow, Hezonja, or [god forbid] Johnson, then Danny should do everything possibly to make sure he gets Upshaw.
