The Chicago Bears have never fired a coach midseason. Here’s a look at how past coaches have fared — and when they left the franchise.

Why he left: The founder and owner of the Bears, “Papa Bear” first stepped away after the 1929 season to focus on ownership duties but returned to the head coaching role in the middle of the Great Depression. After the outbreak of World War II, Halas re-elinsted in the Navy and was awarded a Bronze Star. After leaving with the rank of captain, Halas returned to the sidelines in 1946. He took a brief break from coaching in 1956-7 before his fourth and final stint before retiring from coaching.
