This scenario also is much simpler than the first one I came up with, but it involves Hield (which I personally don’t think GSW would go for).
The Heat pick up Kuminga on a 4-year, $120–125M deal, which is about what’s expected.
The Warriors get back Wiggins and a first-round pick from Miami (top 5 protected), plus Ochai Agbaji from Toronto.
The Raptors add a much needed shooter on a good contract and get some future draft capital from GSW.
