Let's examine that 'bias'. Ravens had 18 first downs, Bills had 16. Each team had one turnover. Ravens won the yardage battle by 48 yards and the TOP by two minutes and 49 seconds. You think the difference in the game was 'ridiculously questionable calls' in the Bills' favor without mentioning the awful drops by our pass catchers and the fact that the 25% of the Ravens yards (not to mention the difference in the final score) came from a single very uncharacteristic busted coverage.
You seem very resistant to the idea that the Bills are a good football team for some reason.
