uh, 6'3 230 pounds is still a big man by todays standards, and Peat was there for nothing short of fighting, so he was good and beat most people he fought. There are a ton of excellent Hockey fighters who just lack the normal playing skill enough to make them liabilities on the ice. Peat was a very good fighter, but not a good hockey player, thus, his low survival time in the NHL. That was ultimately what happened to Stock. Great fighter who won a lot of the time, but poorer Hockey Skills.
Off the top of my head, Stock fought Scott Stevens at one point, Wade Belak multiple times(6'5, 220), Matthew Barnaby, Kris King, Chris Neil, Rob Ray multiple times, Eric Godard(6'4 214), Stephane Quintal multiple times(6'3 230), Gino Odjick(6'3 224), Reed Low(6'4 220)
I know you are not going to question Gino Odjick's fight card. Stock went toe to toe with him and probably gets the decision.
Reed Low had a huge size advantage and all he was in the league for was fighting.
Vs Scott Stevens
vs Wade Belak #1
vs Jody Shelley(6'4 230)
Its really hard for me to just think up who the great smaller fighters were, especially with Dropyourgloves.com being down.
Rob Ray was a great fighter for many years, and he is just under 6'0. Tie Domi as well was only 5'10 210, etc
Why Don't you just go check youtube rather than make me look up all these fights. The fact of the matter is, P.J Stock was a very small man and was a very successful enforcer in the modern era.
