It's building up to be quite the year for Chicago Bears linebacker Khalil Mack. 

He was named the #3 player in the league by NFL.com and said his main focus is winning the Super Bowl this year. 

While winning the Super Bowl is pretty much every players goal every year, Mack's work ethic since coming to Chicago definitely proves the linebacker is on a mission. 

During training camp this week we saw a classic example of Mack going 100%, 100% of the time. 

Mack absolutely crushed a Bears staffer holding the bag during drills.
