Recency bias is a general human problem, but it especially plagues sports fans. We often overrate a big win or loss in the most recent weekend and prioritize that over all our prior knowledge of a team -- both the season to date and what we knew coming into the season.
The Tennessee Titans did not look good in losing to Jacksonville last Thursday night, but their most recent game is not their only game. All the data we have suggests that the Titans are not a great team, but they're a little better than the team they play on Sunday, the Atlanta Falcons.
