The moron who brought the “Toronto Stronger” sign to Game 3 of the Bruins-Leafs series does not represent an entire fan base, so we can’t cast dispersions on all Leafs fans. What we can do is point on some overall differences in the two fan bases. Boston fans are notoriously rabid. The Blue Jays have trouble filling the Rogers Centre. In fact, Toronto’s home ballpark has been known to fill up with more Red Sox fans than Blue Jays in recent years. As for Leafs fans: What’s with the scarves?
