I disagree. Some I wouldn't consider an upset. Some I think are. I wouldn't consider Buccs at Falcons, Raiders at Patriots, Panthers at Jaguars, 49ers at Seahawks, Lions at Packers, Texans at Rams or Ravens at Bills as upset games.
However, Saints over Cardinals, Cowboys over Eagles, Chargers over Chiefs, Giants over Commanders, Browns over Bengals, Jets over Steelers and Titans over Broncos are all possible upset outcomes
