The football team changed to just the Warriors a few years ago. Some of the other school sports are still the Rainbow Warriors though. It's an odd system they have.
It's a shade of red. I just want to know why "Cardinals" didn't show in the NFL and MLB also. Yes "cardinal" is a color - and the team name of Stanford - but "Browns" and "Reds" were there...
The Arizona Cardinals (NFL), Louisville Cardinals (CFB) and St. Louis Cardinals (MLB) are all named after the birds. Stanford's teams were named after their team color when the school dropped the previous nickname.
If you're going down to the college football level, you should include the professional CFL. That would add the Winnipeg Blue Bombers and Ottawa RedBlacks. Also, time to add the Vegas Golden Knights.
It's not really that far "down" to the college football level. Big-time programs like Alabama, Michigan, and Texas actually generate a whole lot more revenue than many NHL and MLS teams do.
But the players aren't paid, which makes them amateurs. There are six major (professional) leagues in North America (the "Big 6"). The professional CFL didn't make the cut, but the amateur NCAA did.
There is a color called tar heel blue more also called Carolina blue after the school. I don't think it should be included but it is food for though. If you describe something and say it's tar heel colored. A decent portion of the US population will know exactly what you are describing.
I think you have to include the baseball team St Louis Cardinals, especially if you are accepting Stanford Cardinal. Cardinals may refer to the bird but Redskin refers to American Indians and the Browns refers to a person's last name. No relation to the colors but has a color in the name.
college football - auburn and navy
Diablos Rojos del Toluca
Cruz Azul
Gallos Blancos
and maybe more.
My point here is that North America is not only the USA.
Either changing the name of the quiz or adding more leagues would fix it.
There's a major spike in the stats right around 10, then it slips away.
