Year-by-year improvement is necessary to build a sustained contender in the NFL. The Dallas Cowboys have failed to build a sustained contender since the 90s, only making the playoffs in back-to-back years once (2006-07).
This year, Jason Garrett and Co. are looking to build off a 9-7 season where the Cowboys were forced to watch the playoffs from their couches, just like the rest of us. Dallas is going to need to improve in multiple areas to have the privilege of playing football into late January.
The idea of improving may bewilder many of the Cowboys faithful.
