There's been a team in New England that hasn't had to go "all-in" to be competitive year after year. To a lesser extent Pittsburgh and Baltimore have done the same thing.
You know how to keep a team competitive year after year?
Draft better than the other guys, don't make stupid trades and jettison players a year early rather than a year late.
Face it, the Cowboys history with "all-in" isn't too sterling.
Then you have others like the Commanders and Eagles who've gone down that path too and failed miserably.
Regardless, we'll all soon know which path this year's version of the Cowboys is taking.
