Bradley Beal had a no trade clause, a super max, has been injured the last two years and is a smaller guy who has never played defense entering his age 30 season and still returned positive value in a trade. Not a lot of positive value, but clearly not a dump.
Jaylen could suffer some catastrophic career ending injury, that's possible. But Bradley Beal is sort of the reasonable (ie bottom tier but not absolute bottom) worst case scenario to a Jaylen Brown super max contract and that wasn't even so bad.
So ya, give him the Supermax. Work it out later.
But DO NOT give his a no trade.
