I feel like if I did that I'd just regret it when I inevitably started to watch the NHL again whenever it comes back. As much as I hate to say it I'll probably always watch when it's there...no matter what wrong it does. To stop watching the NHL would take away so much fun for me...HNIC, Fantasy hockey, etc.
Anyhoo, kudos to this guy for taking a stand...but I too wonder if he'll regret it if/when he starts watching hockey again. Unless he was doing it just for the spotlight in which case job well done.
