Yeah, unless you want to trade Brown, we are not going to be in on Simmons. And even Brown isn't what they want. They want a vet. A fully established player.
I think a trade of Simmons + Maxey (maybe picks?) for Beal is pretty good for both teams. Beal would be a great fit next to Embiid. Simmons and Maxey join a young, rebuilding team. Washington may not be ready to trade Beal, but it may be inevitable, and this may be the best deal they ever see.
