I can't believe Olympic hung a number like that. All Minnesota home games they average 3 goals. I know the juice is high, but it should be a 4.5 goal line, not 5, so I think the worst is that they push.
After reading your post I jumped on the under. I had been playing Buffalo under (both them individually and their games) early on in the season. 1-0, you can't do much better than that.
Good to hear that you cashed. The thing I can tell you is that if they hang a 5 goal line for most Minnesota home games they are going to crash and burn even if it's a -150 line. The only teams that I wouldn't bet this trend is Atlanta, Ottawa and some other high scoring teams.
