In Canada I'm convinced this should be a national holiday, eh!
I work from home so I'm following it religiously anyways.
One of the things I like about hockey is following the roster lineups, trades, cap implications, draft, etc. The whole management side of hockey appeals more to me. I find this more entertaining then pretty much any games outside of actual playoff hockey.
I have friends who watch the games all the time and don't have a grasp on most teams rosters outside their own. They enjoy watching the hockey and it starts and ends there. For me, I wouldn't even be able to get into if I didn't know the rosters, opponents, etc.
