That should just about do it. The Cowboys came out as flat as two-week old soda against the Eagles in the most important game of the 2019 season. The abysmal performance by the Cowboys should be the deed that finally does in Jason Garrett. Sure, there is always the possibility that the Eagles somehow dump a game next week against the New York Giants, and simultaneously the Cowboys beat Washington, but how likely is that? Back in reality, the Cowboys just busted their 2019 season and likely did in head coach Jason Garrett.
