Some of which the refs control and others they don't. I'm not saying it was the refs fault but their calls definitely helped the Chiefs more than Bills. Toss in possible missed calls. I'm upset but letter it fester isn't going to do anything but more upset and why should I do it myself? It's not worth the wasting the emotion on. So I'll keeping on rooting the Bills win and only emotion that will ever take over me if if/when we win a Super Bowl.
