I thought we would see at least a 6 1/2 total after 10 goals were scored in the Blackhawks' 6-4 opening game win on Saturday. I liked the Over very much in that game. I see no reason to change especially with the oddsmaker stubbornly sticking with an opening total of 6 minus juice to the Over. 
The Blackhawks launched 42 shots on goal in that game. The Blackhawks win with offense so they are not going to change their aggressive style. The Oilers were not sharp defensively. Edmonton also is likely to switch goalies going from veteran Mike Smith to Mikko Koskinen, who has never started a playoff game. 
I expect the Oilers to come out firing, too. They have the two leading point-scorers in the league, Leon Draisaitl and Connor McDavid, who has looked fresh and frisky coming off the long layoff. 
The Over has won six of the past seven times the teams have met in Edmonton.
