Khalil Mack was sensational during his rookie campaign, leading ALL defensive players in Pro Football Focus’ run-stopping grade for the majority of the season.

Up until the final game against the Denver Broncos, Mack was second in PFF’s grading, behind only JJ Watt.

Not enough can be said about how good Mack was this season. The sky is the limit for how special of a player Khalil can be.

In Mack’s just second professional game, it was evident that the Raiders had a very good player on their hands.

In the first clip, Mack uses a hesitation to the right followed by a quick burst to the left on Duane Brown (a Pro-Bowl LT), and Ryan Fitzpatrick pays the price.

Only one week later, against New England, Mack was a nightmare for Nate Solder. In the first clip of this game, Mack gets his hands in Solder’s chest and uses his power to drive him three yards back, nearly making the play on Tom Brady. These plays don’t show up in the box score, but have a huge impact on the game.

Again against the Patriots, this time, Mack gets the hit on Brady. He showcases his first step and pure speed, causing an incomplete pass.

The fun continues for Solder. Mack hits him with a spin move that gets Solder off balanced, and then knocks him over to finish the spin. Nasty.
