The trade that sent Khalil Mack from the then-Oakland Raiders to the Chicago Bears in 2018 forever changed how teams part ways with their future draft capital in megadeals for star players.
The Bears acquired Mack from the Raiders in September 2018 in exchange for a slew of draft picks, including two first-round selections, and the star linebacker went on to sign a six-year, $141 million deal with Chicago.
At the time, it was uncommon for teams to part with so much high-level draft capital, but now it has become more common, and several NFL coaches and general managers believed the deal "opened the floodgates" for the megatrades that have happened since, per Sports Illustrated's Gilberto Manzano.
