This is why I'd probably be a bad GM in terms of not actually being able to pull the trigger on a trade. If I were trading with Houston, I find so many of their players to be so similar that I would want several back in a trade. for example, this 3 way works financially:
Boston
Gives: Pierce
Gets: Delfino, Aldrich, Jones, Motiejunas, Parsons, Smith
Has to cut: Wilcox, Collins, Barbosa
Indiana:
Gives: Ben Hansbrough, Granger
Gets: Pierce
Houston:
Gives: Delfino, Aldrich, Jones, Motiejunas, Parsons, Smith
Gets: Granger, Ben Hansbrough
So Indiand upgrades Granger to Pierce and saves some money. They have to include 1 small contract with Granger to make the money work.
Houston likely doesn't do this. But the challenge for them is unless they are giving up Lin or Asik, they need to include a bunch of small contracts; in this case Delfino and Aldrich are just salary filler, while the rest are the meat of the trade. I don't know if Houston would give all that up for Granger, but I probably would take that.
