Read all about it here: Bills fans want game in Toronto to be played under an open dome - NFL - CBSSports.com Football Here's the short version: the Bills thought they would improve their popularity (and thus revenue) by playing in Toronto once a year. However, they've effectively shot themselves in the foot because this Sunday's game is against the Dolphins, and the owners of the Sky Dome are refusing to open the retractable roof. Hence the game will be played indoors, negating the Bills' "home-field advantage" of hosting the Dolphins in December. And on top of it, the game hasn't even sold out. They might as well have just played both games in Miami.
