Some here seem to adhere to the theory that the key to the Cowboys success will lay in a particular coaching scheme, or in-game adjustments, or addititonal 'trickeration'. But I gotta say that what I witnessed during the most successful stretch in team history - the 90s teams - the game plan wasn't all that complicated. The beauty of those teams literally WAS in their execution and well-timed player substitutions on defense (keep 'em fresh) - combined with the AGGRESSIVE NATURE of Jimmy Johnson's decision-making, which was understood by his coaching staff and filtered down to the players. Jimmy would almost always do what he figured would keep the opponent rocked back on their heels. And he would make those decisions quickly - giving opponent coaches little time to process their next move. He DID NOT burn timeouts.
Emmitt between the tackles. Irvin on seemingly endless slants (guy was fearless in traffic and caught just about anything in his wheelhouse). TEs like Novacek that routinely found the soft spot in the secondary and provided the dart-throwing Aikman with a safety valve in case he couldn't hook up with his primary targets. A defensive line that came after opposing QBs in wave after fresh wave. LBers that could run sideline-to-sideline and also brought the wood. A secondary that didn't just chase receivers all over the field but also understood a receivers 'tells', could track the ball, took good angles, and were adept tacklers. I don't mean to leave out key contributors but they were too numerous to mention them all.
The general game plan was 'this is what we do - try and stop us'. Literally zero sleight-of-hand... just blood and guts and victories.
Last year the team had a cohesion that I just am not seeing this year. To a man, players need to realize that they are currently 'walking the plank' together - and that many will not be returning if they don't right this ship immediately.
