I remember the 2011 game in Vancouver. It was a very entertaining game and part of the Grey Cup experience. While I understand the cold aspect of playing in many Grey Cup cities, I like the idea of playing in the same city on Saturday.
If fans in a Grey Cup game city are going to shy away from cold, what does that say about support for Canadian players? Isn't that the goal? Isn't that why we retain the ratio?
It's easier for me to say living in a city with a covered stadium. However I think it's important to send out the fans in whatever city the game is played, cold / snow or rain.
Conversely, if that isn't the model at the moment I'd be in favor of the game in Winnipeg in 2020.
Attendance in 2016 was 7115 and only 10754 in 2017. Decoupling from same city as Grey Cup caused massive decline in attendance and viewership.
It was only do-able in Toronto and Vancouver because of the covered stadiums. There was/is always a concern that the field would be torn up with a game happening the day before.
