Last week, nearly four years to the day after acquiring Kevin Garnett and Paul Pierce from the Boston Celtics, the Brooklyn Nets traded Brook Lopez to the Los Angeles Lakers for D’Angelo Russell and Timofey Mozgov. Lopez, of course, was the last remaining member of that Big 5 that never was. He survived the disintegration of Brooklyn’s “superteam” and the win-less, pick-less, hopeless few years since. That Boston trade will go down as one of the worst deals in NBA history. It’s no exaggeration to say the Nets traded everything – draft picks, expiring contracts, their whole damn future – for nothing.
