Just six weeks into the NFL season, we can be pretty sure there are no great teams. There are certainly no unbeatable teams.
The San Francisco 49ers lost in an early game Sunday, and the Philadelphia Eagles lost in the late afternoon window, leaving the NFL with no undefeated teams two weeks before Halloween. It wasn't just the 49ers and Eagles losing. The Buffalo Bills looked bad but escaped with a win over the New York Giants. On Thursday night, the Kansas City Chiefs had a hard time putting away the Denver Broncos.
