Sean Marks’ legacy may come down to betting on Brown. 

The Nets have had a busy month of decisions, from the Julius Randle trade to Michael Porter Jr. extension to how to use the rest of their cap room. But down the road, whether Marks is still Brooklyn’s GM or not, his legacy may well be remembered by the call he made Tuesday night.

Might well be choosing Mikel Brown Jr. over Darius Acuff Jr., just as The Post projected he would.

That’s probably reductive. Technically, Marks picked Brown over not just Acuff but a litany of prospects — including Kingston Flemings and Brayden Burries, Nate Ament and Aday Mara. But realistically? Brown and Acuff are going to be linked because Marks drafted the Louisville freshman sixth overall, and Acuff came off the board one spot later to Sacramento.
