What I do is use an app called WebApps. You can then search for NHL an pin NHL.com to your home screen. It just opens up the site but without web browser boaders etc. Good enough for most of the time.
"This content requires the Adobe Flash Player" To bad Gamecenter Live on nhl.com won't work. They have an app for BB but not for W8 They don't even have a mobile version of NHL.com, what's up with that...?
