This also how I see it, once Klay return playing the center of their offense is again for the splash bro but they need to have defenders who can run and that's how Simmons will work, he might not a good offensive shooter but with an open floor in front of him he can surely make a damage he's still young his legs still fresh to run together with Green, Iggy, Klay and Steph.
Waiting for that trade to happened, I don't see wiggins as a good addition to GSW, my opinion though.

The problem is that Wiggins salary is about 30 million a year, and other teams do not really like to pay him that much money, why would anyone pay 30 million dollars for wiggins? Which means that warriors needs to give a lot more and get very little to send Wiggins. Sixers? Why would they get Wiggins? That is not really a good thing at all for them, Wiggins would not help them at all and they need a lot more than Wiggins for this trade to make sense.
Most teams closed the door for Simmons because Sixers asked for a lot, like literally nearly a star level player, for example Wizards were asked for Beal, do you really think that Wizards would be willing to send Beal for Simmons? Wiggins basically is what half of Beal is, Sixers will not accept that at all. At the end of the day we should be looking into Simmons possibly staying at Sixers because Sixers couldn't find a trade.
