Oakland Raiders linebacker Malcolm Smith has insisted that teammate Khalil Mack is the most dominant player he has ever seen.

Smith believes that Mack can go on and become a bigger disruptive force than any player from the Seattle Seahawks roster.

"I have played with some pretty good players and he is by far the most dominant that I have seen," Smith said, according to the San Francisco Chronicle.

"He has everything you want athletically, smart."

Mack recorded two sacks, a forced fumble and a handful of quarterback hurries against the Arizona Cardinals last week in pre-season action.
