Do they? The team in 2nd won 3 superbowls and went to 4. It seems to me they mean something. Not to mention we're 3-0 the last 3 times we faced the Chiefs in arrowhead in the regular season. Without the Chiefs we win 1, probably 2 superbowls. Its really unfortunate we gave them Mahomes. I chalk it up to Bills luck.
This might be the only true answer. It would make everything make sense. We're building a new stadium in the same spot, something only the Bills would do.
