Just looked at our scoring over the past 2 decades. The only time we scored as many as 17 goals in the first 4 games I believe was the 2004-2005 season (15 years ago) and the last time we scored more than 17 was the 2001-2001 season - a total of 19 goals (18 years ago). Of course much of this may be dependent upon the competition and this year that may not stack up well against our usual first 4 opponents. Not an absolute comparison but some years like 2011-2012 it took us until our 15th game to score our 17th goal.
Although this may all be comparing apples to potatoes, still nice to see a bit of offensive explosion early in the season.
