I think part of the complication, especially if the Warriors want to hold onto Kuminga, is what to do with Wiggins. I'm sure the Warriors are desperate to move him and especially so if they're now paying both JK and Lauri big money. The other complication is unlocking their 29 and 31 picks. It shouldn't be that hard to get it back, but just with everything on the table the easiest path to get that pick would be for UTA to have the sweetner to send to WAS. So we're doing them this huge favor by taking on Wiggins and doing them a favor by unlocking their picks....Ainge is going to want payment for all of that.
When you think about the cost of taking on Wiggins, it's got to be like a 2FRP worth dump. The Warriors might be running out of stuff at that point if you're counting the value of Lauri, the value of the dump, and the value of the sweetner for WAS.
