San Jose can score. The Sharks have demonstrated that in producing at least three goals in five of their seven games. However, that's negated by the Sharks ranking 30th defensively allowing an average of four goals per game. 
The Sharks have permitted three or more goals in all but one of their seven games. Included in that is a 7-3 Colorado victory against San Jose at home two days ago. 
The Avalanche have scored 15 goals during their last two games. The Sharks are playing for the fourth time in seven days. They aren't helped playing again in Denver's high altitude. High altitude could be a reason why the Over has won seven of the past eight times in Colorado home games. 
This series has an Over bias, too, with the high side going 19-7-3 the last 29 times.
