Well, no. It's not about Western vs Eastern.
It's only been for like 25 years that the Jets have been in the NHL. So, if you were watching the NHL, you needed another team.
Also, the Blue Jays suck. Go Yankees!
When the NBA expanded, I cheered for the Grizzlies and even caught a couple of games when I lived in the GVA. I cheer for the Raps now but they are not my favourite team. I don't really have one. But, you see them all the time on TV and become familiar with players and the org. Same with the Jays. You know what you see.
