NHL preseason betting is probably one of the least understood and least bet sports. How do we begin when making a bet on NHL preseason games? NHL betting begins with the odds. You have a basic money line where one team is favored over the other just as you might see in baseball. If you had Detroit playing Chicago you might have the Red Wings at -160 and the Blackhawks at +140 in NHL betting. These NHL preseason betting money lines are simple enough to understand. You are laying 1.6-1 on Detroit and getting 1.4 to 1 on Chicago. You can bet any amount within the limits set by the sportsbook at the corresponding ratios.
