I see no realistic way to sign Beal in free agency without a sign and trade and the sign and trade probably includes moving Brown with either Smart or Richardson.
If that is true, I think the team is taking a step back not forward. Brown and Smart or Brown and Richardson is better than Beal alone. And Beal would need to be given a 4 year, $170+ million contract hurting the team's salary flexibility
I don't care how close Beal and Tatum are, attaining him via next year's free agency will hurt the team in the long run. And I don't see Washington moving Beal here for the smorgasbord of players and picks the C's would need to send them at the deadline in order to keep Brown.
To me, Beal is the wrong guy to target.
