How wrong you are. One is Roughriders while the other went by Rough Riders. As Martin Short once said to David Letterman when describing how you can tell who won when the teams faced each other: "Canadians know who won".
I'm Canadian. I don't know the difference. And a comment by Ed friggin' Grimly on Letterman does not count for shit.
I'd like to add the name Ottawa Naked Bootlegs to the mix as well Although it may cause some conflict with the Halifax Nakedbootlegs of the same name. nah, fuck it. A Canadian would know the difference.
