I am still deeply annoyed with myself for not purchasing a Chiefs Super Rigby plaid shirt when I was in Aotearoa New Zealand because I happen to live in the area where the US football team of the same name plays.
The team colors are the same, but the logos are different. I would enjoy confusing people around town.
However… I don’t know if “chiefs” is any more appropriate for a mascot in other countries than it is in the US.
