Id be interested in making a run at Wiggins. I am not sure there is a deal to be made for him, but:
GSW gets: 2026 FRP (top 10 protected), 2 SRPs, holmes and Davion.
SAC: Wiggins.
Why for GSW: they save 7 million up front and split the contract into more moveable pieces if mitchell and holmes dont work and both are on shorter deals. I dont see GSW competing for another chip as long as Draymond, Klay, Poole, and Wiggins are draining a collective $125M in addition to the $51M that steph will make. Problems for them is Draymond is likely going to opts in to his $27M and they just signed poole to stupid money ($28-30M) and no-one will likely touch Klay for his $43M this year, nor do i think they will like ti move on from Klay... So wiggins is the only piece people will want that can make a dent in your financials...plus they get a backup PG to hide poole defensively and allow him to be SG.
Why for SAC: While i hate to lose Davion, you gotta lose a good piece to get a better piece. You will add Wiggins who is an elite level defender with a far better offensive punch than HB (whose spot in the starting lineup he'd take). It allows you to move HB to the bench (if you resign him to a reasonable deal) bringing tremendous stability to the bench and some better length and defensive versatility while you continue to develop Kessler Edwards. It also enables you to run Wiggins, HB AND Murray together which is a long and reasonable defensive line up.
