Malcolm Smith: 'Khalil Mack most dominant I have seen'

Oakland Raiders' free agent acquisition Malcolm Smith has said that his new teammate Khalil Mack is the most dominant player he has ever seen.

The 26-year-old was a part of the Seattle Seahawks' 2013 Super Bowl-winning defence but despite the talent he has displayed in the past, Smith feels that Mack is one of a kind.

The linebacker told the San Francisco Chronicle: "I have played with some pretty good players ... and he is by far the most dominant that I have seen. He has everything you want athletically, smart."

Mack started every game for Oakland last season, finishing with 59 tackles, four sacks and a forced fumble.

Smith spent four years with the Seahawks before joining the Raiders this summer and will make his regular season debut against the Bengals a week on Sunday.
