To bad if the splash brothers will be separated since we know how exciting to see them play together with Steph. But that's how business works on NBA and maybe the owner can't handle to pay huge luxury tax anymore and they need to create a big move so they can build up their team into a title contender without paying another huge taxes again.
They are exciting to watch before but Thompson's performance have declined and he is not anymore showing great percentage of his outside shooting. So as you've said, business is business, they need to rebuild the Warriors with a new players coming in while letting out those who are high paid players like Thompson. I would even want Wiggins as well to be traded so they'll have plenty of room to get a new players that could blend with Curry, it's time to try for a new experiment since they failed badly last season.
Agree to that, it's business and if they see (management) don't get any decent outcome then they will find ways to make it benificial on both ends, same with your statement, Klay is no longer the same even they manage to win another title after his injury, his performances is now lowering, they need to free some cap and if they manage to let Klay and Wiggins go, then they can get a new star/s that might be fit for Steph, they need to experiment as the current squad is not that competitive they need new sets of players that might help Steph in trying to win another title for the franchise.
