For a seven-year period between 2004 and 2010, the NFC West was the divisional laughingstock of the NFL. The division posted a .400 winning percentage during that span, with three of its four teams losing at least 16 more games than they won. And only six teams finished seasons with winning records. In 2010, the Seattle Seahawks won the division despite finishing 7-9, and nine wins were enough to win the division in 2004, 2006 and 2008.
So for the better part of a decade, the NFC West wasn't just the worst division in football, but by far the worst division in the NFL and one of the worst in professional sports.
