In the summer of 2013, the Celtics and Nets made one of the more impactful trades in recent NBA history, as franchise pillars Kevin Garnett and Paul Pierce were sent to Brooklyn in exchange for what proved to be a bountiful haul of draft picks.
At the time of the trade, it seemed like a potentially crowning achievement for the Nets, providing the roster with a critical mass of talent to chase a championship. The Celtics, meanwhile, were plunged into a rebuilding effort. Yet within only a few years, the fortunes of the two teams reversed.
The fallout from the trade has eventually made it a cautionary tale for NBA general managers.
