It's a day reserved for drinking and wearing green. There's nothing I can do to help you with the drinking part, but maybe you'll like some of these green concept jerseys.
Of course don't forget that the New Jersey Devils will crack out their 1980s throwback sweater — a swell mix of red and green — for one night only this season. That'll be tomorrow when they host the Capitals (they're in Ottawa tonight). They Devils wore them for the first time since 1992 last season on St. Patrick's Day.
Saw someone mention in the comments a desire for a green Quebec concept, then realized I had one filed away for a rainy day. Let it rain!
Happy St. Patrick's Day from Icethetics!
