Golden Knights vs Mammoth Prediction 

Utah played pretty well in the first two periods of game one, but they fell apart in the third and couldn’t get the win. The Mammoth were 21-17-3 on the road this year, while the Golden Knights were 20-12-9 at home. Vegas has been red hot over the last few weeks and they won the Pacific, but they had plenty of trouble in game one and they lost the season series to Utah. I think the Mammoth will give Vegas some trouble in this series and they should be playing with plenty of confidence after how they started game one. Take Utah and the plus money here.
