Both teams are currently showing the best form in the NHL - Boston have won 4 of their last 5 games, while Buffalo have a streak of 5 straight wins. The home team looks nominally the favourites, but Buffalo have an incredible execution right now (scoring an average of 4 goals per game), so it's better to bet on the total.
Prediction: at least 6 goals to be scored. We recommend the "Over 5.5" bet, odds 1.65
