You know it's a problem when athletes have to use smelling salts to "wake up" (as some of them have put it) before an NHL game because adrenaline isn't enough.. I mean hell when I started playing hockey a few years back I had my first run-in with the boards and didn't even go in that hard, but still had an achy feeling and my head was foggy..
Can't imagine what that's like multiplied out for these guys who play at elite levels for years.. And players are bigger, faster, stronger now.. I really believe they need to bite the bullet and switch to Olympic sized rinks because making all of these rule changes is only a bandaid on the issue
Ken Dryden was on hockey night live and mentioned how back in his days, players would play 2 minute shifts, and they would coast and circle till there was a need to go full throttle, so for the most part it was a much slower game. Now every shift is only 40 seconds and full throttle by younger better fit men and the results are serious collisions that cause serious injuries.
I would personally like the bigger ice surface, but that would make the game even faster.
