The source I used has them included in the New York City metro. And it's no stretch of the imagination to figure it out. The arenas are 30 minutes apart.
Can you separate Anaheim Ducks and Angels from Los Angeles. I know it's correct that it's there, but I always think Anaheim when I hear the Ducks and Angels. Those were the only 2 I missed.
The source I used has them all grouped together, because they're so close. It's the same way with the Devils being included in NYC. As a side to that they are known more as the Los Angeles Angels. Usually people drop the "of Anaheim" part.
* Niners
* Nats
* Sixers
* Pats
* Blazers
* Jags
It's a good quiz but these are pretty standard and would improve it.
