The teams just played one another two days ago. There were 69 shots on goal and eight goals scored with Carolina winning, 5-3. 
The Hurricanes are the ninth-highest scoring team and rank third in the league in shots on goal. Carolina is averaging 4.1 goals in its last seven games. 
The Stars are the 11th-highest scoring team in the NHL with the league's fifth-best power play percentage.
Another reason I favor at least six goals being scored is the goalie situations. The Hurricanes are going with veteran James Reimer as Petr Mrazek is out indefinitely with a thumb injury. I expect Reimer to get worse and worse the longer he has to keep playing. 
Meanwhile 34-year-old former backup goalie Anton Khudobin is off to a slow start for Dallas giving indications that his stellar playoff performances from last season may have been a fluke. Opponents have scored 17 goals the past four games Khuodbin has been in goal. The Hurricanes have scored 13 goals in the three games they've faced Khudobin this season.
