That is because Jason Garrett only made the playoffs 3 times in his 10 yr tenure as head coach................he missed the playoffs 70% of the time.
Fat Mike has been here 4 years and has made the playoffs 3 times already and the one year he missed the playoffs was the Covid year.
I'm sorry, but if one coach misses the playoffs 70% of the time and the other coach makes the playoffs 75% of the time and could have been 100% of the time if not for a world wide pandemic, then there is no comparison to be made. Jason Garrett was the most unqualified, untalented, and undeserving head coach the Cowboys have ever had and Fat Mike getting beat in the 1st round every single year does not change that.
