it
could do that, but not every guy who has a big bear on his back is able (or even willing) to throw a punch. maybe a big guy like lemieux would be able to handle himself in a scuffle, but i wouldnt want to be a small guy and have that as my only option to keep the game fluid. let the refs control the clutch and grab, they are on the ice at all times (at least physically)
using fighting as self-regulation is a good idea, but it can only be stretched do far.
