He actually has fought a bunch of those guys you listed.
I looked this up for another post a while ago, but it seems relevant to this thread. To get an idea of who he's going up against.
Ryane Clowe's career fights:
Krys Barch (3)
Sheldon Brookbank (3)
Jeff Cowan (2)
BJ Crombeen (3)
Matt Greene (3)
Tim Jackman (4)
Jamal Mayers (2)
Daniel Winnik (2)
If you want to go off of the voting at Hockeyfights.com (which isn't exactly scientific, but short of watching all the videos and judging yourself)
He has 32 wins, 13 draws, and 5 losses. Personally as a Shark fan I can't remember the last time I saw him lose a fight.
After watching him not beat Fraser, he should not be fighting Orr, Mclaren, Engelland, Parros, Scott, Carkner and crew.
Except hes turned Parros inside out and fought Engelland a couple times to draws. This is going to come across as me leaf hating again probably but Fraser had his good arm out of his sleeve most of that fight and still couldnt get a really clear decisive win off Clowe with that obvious advantage.
I dont think that fight should give you much of an idea of who he should be fighting. Fraser is 6'4, has 17 fights this year and fights legit tough guys. Clowe has one fight where the guys arm is out of his sleeve the whole time and still fights it close and has an incredible win loss record but now he should fight other guys like that?
