VIDEO: Khalil Mack with a magistral game in his Chargers' debut.

The Bears decided to trade away their best player in EDGE Khalil Mack this off-season in exchange for a 2nd round pick. While it seemed like the right decision at the time, it was still difficult to digest the fact that Mack would not be wearing the orange and blue.

Well, it looks like he picked off right where he left off during his first game with his newest team, the Los Angeles Chargers. Indeed, Mack was by far the best player on the field and he was, quite frankly, the biggest reason why his team won. His Chargers debut was a success as he tallied six tackles, four quarterback hits, and three sacks, the last of which ended the Raiders' last-ditch comeback on a fourth-down pass play.
