Not disputing your observations at all but that is likely influenced by how long the teams have existed and how long their season tickets have been held in families. Lots of Leaf season tickets are held by folks who have had them in their families for multiple decades.......back when Toronto was a bit more uni-cultural than multi-cultural....so it stands to reason the crowd would reflect that in some percentage....it also might influence the ages of the people there.Well, I would say Raptors fans include white people but also non-white people as well, maybe fairly equal percentages of each racial group.
Whereas the last Leafs game I went to was probably >80% white, and also the average age seemed much older.
It is all anecdotal stuff (as others have noted) but I know that here at the office when we have Raptor tickets that are unused and available on a last minute basis for staff to use it always seems to take longer to find a staffer to take them than when we have Leaf tickets.....and, in direct comparison, our Raptor tickets are a bit better/sexier than our Leaf tickets.
I think a certain amount (not all but some) of the younger, hipper, more multi-cultural crowd at Raptor games is due to the fact that those tickets are bit easier to find and the city had evolved before they were available.....and people do like to "do stuff" and "get out there".
The feel I get is that the Leafs are still (for how long I don't know) the straw stirring the Toronto sports drink.
