Ouu... I seem to have struck a nerve of many western CFL fans.
I am fully aware of displaced Saskatchewanians across this country. This however can't account for 30-40% of McMahon Stadium being green. The majority of these must have made the trip. And who cares if Saskatchewan is only supported on the road because of displaced natives? They still manage respectable crowds at home as well as the best road support in the league.
I wouldn't argue over a slightly smaller home-gate for the Riders either. The population of Saskatchewan (the province) is 980,000. From a fan-base across an entire province comparable to one of any other city in Canada, these Rider fans put up comparable average attendances albeit slightly less than all cities other than Montreal for their small stadium.
I'm a Ti-Cats fan but I will single out the Riders for having the best fans in the league.
