Hitting is still in the game, just not predatory hits. Apparently that draws the ire of the inner Don Cherry in people that think that means the league is gone the way of a pansy sport. Hardly the case. Having more respect for their peers is not a bad thing at all, you can still throw a hard hit without it being high or predatory.
As for fighting, enforcers aren't doing it as much anymore and for obvious reasons - How many ex enforcers are dying and talking about severe depression and CTE issues? You think they think that's worth it now? If anything, teams want players that can also take a regular shift, if that means the plugs that just fight and do nothing else are being phased out with fighting, fine by me. Saves a bunch of lives too, down the road with concussion and other mental issues that come along with punches to the head.
Most are always a really bad high stick near their eye, from wearing one.
