If ARZ needs to hit the cap floor, and ownership does not want to spend to the floor, it'd create a different dynamic than with the Bolland trade. I still think CHI or another team would have to pay, but because it is a win-win situation, I don't think it'd be nearly as much as in the past.
With that said, there's no guarantee ARZ isn't willing to spend to the cap floor. If they are already willing to do that, then the dynamic shifts and yeah it'd probably cost something similar to what it has in the past for those kind of contracts to get moved.
