Top 20 Most Impactful Acquisitions of 2018

4. Khalil Mack

The Chicago Bears won the NFC North for the first time since 2010 this year, in large part due to the play of their defense. While there are plenty of talented players to point to for their success, one stands out above all the rest.

Khalil Mack.

Mack was traded to the Bears from the Raiders and has been worth every single penny of massive extension that they signed him to following the deal.

Mack has 12.5 sacks, 18 quarterback hits, 10 tackles for a loss and a league-leading six forced fumbles. He has been an absolute monster for them and now looks to lead the Bears on a potential Super Bowl run.
