They were winning though. They were not making the playoffs, for a litany of reasons that start with a bad defense as they still have not won a game where they have not scored 30 since 2018, but when you are rebuilding you don't throw the baby out with the bath water: identify what and who is good and what and who is bad and focus the changes solely on that. Dallas has a top tier QB and considering moving on and playing QB roulette for the next 6-9 years on average on the hopes that MAYBE they get a guy close to as good seems rather crazy to me
