Butler definitely looks like he would be great for Warriors but that doesn't mean that we are looking at something that will get a great deal but at the same time this is not a real trade and not even a rumour but just a thought experiment and nothing more.
That goes for the clout and fans that likes to create rumors are like that.
But if it goes and becomes a real thing, trades like this is going to be a surprising one. What I think is the better rumor and close to reality is about Giannis wanting to move to Dallas.
It's more likely as we've heard it last season IIRC that he wants out of the Milwaukee Bucks.
No way the Bucks move giannis there is no reason too. No reason to take on Dame without having giannis on the team. He is locked in for 3 more years amd then a player option for another one. And I'm not entirely sure he would ever want to leave. A lot of people don't know but the Bucks organization had a huge part in getting his whole family to the united states. There's things outside of basketball which makes people want to stay working for a certain team.
It's just born out of frustrations for Giannis if he wanted to get out of the Bucks. I think it's fair though, last year, they are expecting to have a good team with Dame as the new teammate. Nevertheless, they have a lot of issues, fired their head coach, have a interim that did good for them but eventually replace by Doc Rivers who have been criticized as well.
For Butler, same, maybe he wanted reset of his career and a good destination could be Warriors for him to team up with Steph Curry. But if the Heat will counter offer, not in terms of money, but in terms of players that will surround him, maybe he will stay at least for 2-3 season.
