The Titans have a superior interior defense and superior run defense as a whole.
Not surprising. Nor is it surprising that the Packers had a different game plan against the Titans. The Cowboys run defense and schemes to stop the run are food (as the young kids say). Why wouldn't you eat against Dallas?
Was the difference in the game. We could not stop it and couldn’t get the last score needed to close it. Or that one big play when needed by the Defense to close it.
