New York City population: 8.5 million
Winnipeg population: 700 thousand
You got your answer right there.

To be fair, my NFL team - the Green Bay Packers - are based in a city with a metro area of about 300,000 people and have sold out an 80,000 seat stadium for decades. Then again, they do have in excess of 4 million fans in the USA and Canada, so there's that. The other more pertinent factor is that this is Winnipeg in October, and the temperature yesterday was right around freezing (not even factoring the wind-chill temperature), as evidenced by TSN's clip of Streveler practicing pre-game in snow - as enthused as we all are of the way the Bombers have played as of late, it's a tougher sell to get the casual fan out for a game in conditions like that. Regardless, if it were a playoff game against the same Riders after this showing complete curb-stomping, I guarantee IG Field would be packed, even in November.
