I have no knowledge of Hockey whatsoever. However I'm using a trend based system for the over/under and I'm doing okay. I'll start posting my picks here
Why under 5 in the Calgary/Colorado game? Both teams give up an average of at least 3 goals per game and score an average of at least 2.5 goals per game.
Like I said, not as knowledgable in the NHL as I am other sports, but I've been using trend- based system that started off hot but has cooled as of late. I've noticed that the under has been outperforming the over by about 20% percent so far in the math that I use so perhaps it would be wise to start playing the overs. Oh well, we'll see how tonight holds up!
