This rule could be the framework for the NHLs ban on fighting. First, the QMJHL banned fighting outright. Now, the ECHL, an affiliate of the NHL, has placed much heavier restrictions.
This is just another step towards potentially seeing fighting outright banned in hockey in general. Eventually, the game may be played without dropping the gloves at all and be a watered down version of what it originally one. But, if that is the price for player safety, it is worth it.
