Wow. Not only are you wrong……you are completely dead wrong.
Coaches get fired ALL the time for reasons other than just a bad team.
1). Sometimes a head coach sucks and can’t maximize a team’s ability (see 2019 Cowboys, 2023 A&M with Jimbo Fisher but top ranked receuits, numerous Texas Longhorn teams with tons of talent but crappy coaches, etc etc)
2). Sometimes a head coach has off the field issues and distractions (see the Jaguars with Urban Meyer, Raiders with Gruden, etc etc). Their firings had nothing to do with a “bad team” and everything to do with the head coach themselves.
I mean….wow. Did you even think before you posted?
On top of that, Garrett took over in 2019, and the Cowboys “bad team” miraculously and immediately turned it around and went 5-2 the rest of the season.
So no. The 2019 Cowboys were not a “bad team”. They had a terrible head coach in Wade Phillips that the team gave up on.
Check and mate…
