So Beal can opt out of $37.3M for 2022-23 and sign an extension for 4 years at $45.4M per (FA again at age 32), or play next season for $37.3M and sign for 5 years at $47.0M (FA again at 34). I think he is better off taking the raise next off season. You never know what is going to happen (just ask Oladipo or Schroder). If he is still a top player at 32, he can start doing 1 + 1 contracts and probably end up with close to the same money with less risk.
I almost hate to say it but wouldn't a Beal for Simmons + Maxey + Picks deal make a lot of sense for both teams? Much like I thought Kemba was a perfect fit next to Embiid, Beal is that but better. I am not sure how much better either team could do in a trade involving these players. Washington would be better off keeping Beal and giving him the big contract if they are sure they can keep him happy. Simmons, Maxey, picks may not be a bad return though if you have any concern he may walk at some point.
I know everyone wants Beal on the Celtics but I don't see how we could match this type of offer unless Brown at a minimum is involved (and we likely would have to add more). Philly gets better trading Simons for Beal, a better fit, a better complementary player for Embiid. For us it is more of lateral. Brown is not a bad fit for us, Beal might be a little better. Simmons is a bad fit next to Embiid so much easier for them to give him up (and he wants out).
