I could understand betting on it just not a lot of money. Coin toss is 50/50. I just dont see how anyone could put a large sum on a preseason game , especially the first one. Im assuming the line has a lot to do with back up QBs. In the early to mid 90s, we had the best team in football, but we would get hammered in preseason.
The Bills have a pretty talented squad. If the Cowboys and Bills switched QB's, they would be Super Bowl contenders in the AFC. They are strong at RB, talented at WR, decent OL, and a strong D. Just no QB
