I personally feel like this could easily be the winning offer, better then Simmons, a few FRPs and swaps and Milton. This gets the Warriors a guard who can play next to Beal and be the 2nd option and take pressure off of Curry, and show him they want to win.
If Beal wants to go, Wizards need to trade him, Wiseman, a project who has a high ceiling, 7 with 15, and future FRPs isn't bad.
