Khalil Mack turned heads as a rookie, but the Oakland Raiders linebacker has carved out a clear-cut goal for 2015: More sacks.”I definitely want to get after the quarterback more this year,” said Mack, per ESPN.com. “I got some hits (in 2014), but people didn’t really see what I can do. Those sack numbers I had (four total) really weren’t me. At the end of the day, you want people to see you at your best.”Mack showed plenty last season, finishing the year as a premier run-stuffer and a constant nuisance in the pocket. His game tape matches up with his top overall ranking among all 4-3 outside ‘backers via Pro Football Focus. Second on that list? Denver’s Von Miller.”I think Khalil is way more physical than Von,” said Raiders coach Jack Del Rio, who coached Miller with the Broncos. “Von got up to somewhere around 250 pounds when I had him but he’s naturally closer to 240. Khalil can be up around 260 or 265 and they both play that strongside linebacker position and sub-pass-rusher role. Since most teams use their sub packages for two-thirds of the game, there will be some opportunities there. They’re different but they’re both special.”
