The class difference between these two teams is greater than the lay price in my view. Edmonton has too much offense for a mistake-prone Blackhawks defense. Connor McDavid is at the top of his game. There is no one better in the NHL. 
The Blackhawks caught the Oilers napping in the first period of Game 1 scoring four goals. Since then during the past five periods, the Oilers have outscored the Blackhawks, 9-5. 
Chicago has not done well in quick turnarounds going 9-25 the past 34 times when playing on one day rest.
