This from http://www.predictem.com/nfl/teams-off-bye-weeks.php "Some teams have a track record of playing awfully after the bye, and if a team wasn't good before the time off, chances are, they still won't be good after the bye either." Over the last 10 years, both the Bills and Oakland have been 2-8 after coming off of a bye. The trend? Good teams remain good after the bye and bad teams remain bad.
