Well the oddsmaker wised up a little when it comes to these two teams. The opening totals number was 6 when the Senators and Canucks met two days ago. The Canucks won that game, 7-1, so now the total opens at 6 1/2 with juice to the Under.
Until proven otherwise, I'm going to ride the Over with these two teams in their rematch today. 
These are the two worst defenses in the NHL. Ottawa surrenders 4.5 goals per game. Vancouver gives up 4.25 goals a game.
The Canucks broke out of their scoring slump against the defenseless Senators. The Senators are promising changes. So what? They haven't stopped any team all season. There have been seven or more goals scored in four of Ottawa's six games. 
The Over is 7-1 in Vancouver's games this season. Until holding Ottawa to one goal, the Canucks had permitted at least three goals in every game. 
The Over has cashed in each of the last five games between these teams. 
I see no reason to change course especially since the total hasn't reached 7.
