Garrett was 85-67 during his 10-year run with the team ... and only made the playoffs 3 times despite having some seriously talented players.
Of course, a TON of people think this will open the door for Dallas to be successful once again ... ex-Dallas star Terrell Owens has said repeatedly Garrett was the biggest problem for the Cowboys.

There are all sorts of conflicting reports about why Jerry Jones and the Cowboys waited so long to formally terminate Garrett ... there was speculation Jason was trying to get a front-office role with the team.
Garrett and Jones go wayyyy back ... he won 2 Super Bowls with the team as Troy Aikman's backup QB back in the day.
