I'll echo (from the other side of the border, though) that Bigfoot is not only an oft-used term in the States, I'd guess it's more used there where Sasquatch is here. (All the American programs entitled "Hunting Bigfoot", for example). Plus, the category was about words with native American origins, "bigfoot" obviously isn't.
Was this the first time that a player has been introduced not only by where they live (or, before this season, sometimes where they used to live) but *also* where they work? David was introduced as "an 11th grade history teacher in Peller (?), Texas, from Fort Worth, Texas".
