LAKE FOREST, Ill. -- Bears head coach John Fox earned yet another dubious distinction with Sunday’s loss to San Francisco.

Fox (12-32) moved past Abe Gibron (11-30-1) for sole possession of the worst winning percentage (0.273) in franchise history -- and the Bears still have four games left to play in 2017.

Fox has one fewer win than his predecessor, Marc Trestman (13-19), who lasted only two seasons in Chicago.

Fox is closing in on completing his third -- and likely final -- season with the Bears. Many of the Bears’ problems, of course, date back to before Fox arrived in 2015.

The Bears began their descent into football’s abyss when George McCaskey, who was named team chairman in 2011, signed off on the decision to fire former general manager Jerry Angelo. That move paved the way for the Bears to hire general manager Phil Emery, who fired Lovie Smith (81-63 in the regular season) in favor of Trestman after the team finished 10-6 in 2012.

The Bears are tied for the third-worst record in the league (25-51) since Smith left town after 2012 season. Only the Jaguars and Browns have been worse, but Jacksonville (8-4) might be headed to the playoffs. The Bears, officially eliminated from the playoffs Sunday, have missed the postseason in 10 of the last 11 years.
