The Chicago Bears made one of the biggest trades the NFL has seen in a long time when they acquired Khalil Mack from the Oakland Raiders in 2018.
The Chicago Bears have had their share of mistakes over the past few seasons but they have also had their fair share of triumphs. One of those triumphs is the trade they made with the Oakland Raiders. They sent draft picks to them for Khalil Mack. He was looking for a new contract that the Raiders were just simply not looking to give away at that point in time.
