For me it was losing to BUF at home. A BUF team that came limping in with a horrible defense, on the road, and pulls out a win. Even though we were 4-2 at that point, I started telling people that this team's weaknesses are too great and every team in the league will know we can't run, can't pass protect, and can't stop the run. A lot of my friends told me I was overreacting, but it's looking more and more that I was correct to hit the panic button at 4-2.
