I personally don't know anything about Hockey but one of my friend who is a fanatic, told me to bet Under 5 +110 for game 7. He also said that NHL Finals GM7 always goes under. Don't know if it's true but he is a big NHL fan and knows teams and players by heart.
Take it for what's worth...
Under 5+110 to watch the game
