Knies is 6'3 227 lbs. Who has Bennet fought that is bigger than that and also fights often? The only guy I can think of is Zadorov who turned Bennett into a pretzel.
The only semi tough guys with any size Bennet has ever beaten are Josh Manson and Darnell Nurse who are at least 10 lbs lighter than Knies.
You can find Bennett's fight card below, it's not very impressive, there's no Tom Wilson, Wayne Simmonds, Tanner Jeannot, Lawson Crouse, Trent Frederic, Adam Lowry, Matt Martin Luke Schenn, or even a Pat Maroon. I'm not even including the really tough guys like McDermid, Reaves, Olivier, Deslauriers, Lucic, etc. not sure why some people here think he's Mr. Tough Guy.
He's actually lost his last 3 fights but for some reason he has legendary status here. He's a spot picking clown who would start crying if Reaves even looked at him sideways. Both Benoit and Pacioretty have fought guys a lot tougher than he has.
