I play hockey, so I feel empowered to comment on this subject. A lot of names can be thrown out there when claiming who is currently the best fighter. However, a number of guys come to mind.
First, Matt Johnson (Wild?) is a tussler who took down Brashear in a rough scrap once.
Next is Scott Parker who also fed Brashear his lunch a few times, and rarely loses to anyone. I remember seeing a fight between these two a couple of years ago, when Parker was still on Colorado. He hit Brashear so hard with a shot to the side of the head, his mouthgard flew, horizontally, out of his mouth.
Many people (not on this site) would say that Peter Worrell is top notch, but he's just really tall, with a long reach, nothing special. I've seen Tie Domi, who is significantly shorter (but 10x as feisty) handle Worrell relatively well. Domi has very quick hands, therefore, he's effiecient in a scrap.
Rob Ray is another one of my favorites. He's average height and kind of wirey in build, but he can throw hands with the best of them.
Cam Janssen is not one of the best, but I saw him land some notable shots in game one against a Carolina player the other day. His opponent (I forget who exactly) was a lot bigger then he, but Janssen handled himself well.
I'll give it to Brashear, he can fight. Although he generally picks fights with people significantly smaller then him. But hey, if he wants to be the bully of the schoolyard, then thats his choice.As for general hockey talent...he has none. \
tThis list can go on and on and on, but these are the first players I could think of. Anyone else, please feel free to add onto my list if you want to.
