I wouldn’t mind making some major moves to acquire an all star level player, but that likely means trading Brown. I wouldn’t mind that, but I suspect his trade value has fallen.
This is boring, but I think the best thing to do is trade away Schroder and Richardson, maybe even Smart, for draft picks. Smart might be able to get a mid first, the others might get a late first or more likely multiple seconds each. That will provide more draft capital and give Langford, Nesmith, and Pritchard significant playing time.
Then ride ride out the year with what we have. We’ll get a better idea of the ability of the young guys. We’ll have more time to assess Brown and Tatum’s ability to play together. Ime will have more time to prove himself and for Stevens to evaluate him.
After the season there will be hard decisions to make. Possibly, blow up the team where likely everyone but Tatum will be available and hire a different coach. Hire a veteran coach who can work with Stevens to imagine and create a new vision for the team.
