I'm wholeheartedly in favor of the Jimmy trade.
After being initially against this trade, because I really love Wiggins, and because 60 mil a year for Jimmy is an obvious overpay, after having thought about it for a second I can say I completely agree with it.
This trade does three things that the Warriors desperately needed: 1. It basically forces a change in playstyle, Jimmy won't fit in the current system even if he is asked to do it. His mere presence changes how the team plays. 2. It finally gives the team someone who can take over games whenever Steph can't, which will become more important by the day. 3. It shakes things up. If no trade were made the Warriors would be the same as they've been for the past 3 years: a mid tier team which unattractive to most players in the league. Will the Jimmy trade change that? I don't know, my guess is probably not, but now there is a chance whereas before there wasn't.
And I'll add a bonus point which is that now we finally have another player with a combative mentality who is not Draymond, and who can maybe even keep him in check a little if things don't go sour.
Is 60 mil a year too much for Jimmy Butler? Yes, but it is what the Warriors HAD to pay to get a superstar and buy a chance at anything bigger than the snore fest our last seasons have been. It was the only way.
