Much of this trade discussion is flawed because it is focusing on the Jazz as buyers, trying to fill in the roster around star players, as if the Jazz are ready to contend now. However, to be a contender you need to have either: A) 1 super-star + 1 star, or B) 3 stars. Unfortunately, the Jazz don't have the star power to contend yet. So, until either: A) Donovan develops into a super-star, or B) the Jazz acquire another potential star player, the front office should be in asset accumulation and development mode (i.e., sellers).
So, unless the Jazz think there is a player they can acquire now who will be a star for them, they should focus on trading players on the roster for 1st rounders, players on rookie contracts, or vet players they can rehab into an asset (like Jazz have done with Crowder). For example, I bet we could get a 1st rounder or interesting young player for Crowder (looking at Houston or Wolves). Also, I would reach out to teams that are trying to compete now (e.g., LA, OKC, Portland, New Orleans) to see what they would give for Ingles (Ball or Hart?). Phoenix still needs a PG, let's send them Rubio or Neto. Get Favors to the Wizards for either OPJ or a 1st.
I believe that trades focused on building a supporting roster for this year is what DL would refer to as "skipping steps".
