In fairness going back 6 seasons or whatever you said is also an incomplete picture. They have been a mediocre franchise in a mediocre division for a long time.
I agree with you they did some consistent winning, but never got anywhere. I cant recite winning percentages off the top of my head, but we've had to go against some really tough eagle and giant teams going back to Romo.
The NFC East is and has been a much tougher division over the course of the Texans entering the league imo
That play - Romo juking Watt - in his prime a top 5 NFL defensive player -top ten greatest playCowboys regular season history.
'CowboysWillRise' - I surmise you live in metro Houston \ Texas Gulf Coast / East Texas = Texans' fan base --so you get a daily \ weekly barrage of anti- Cowboys rhetoric
The NFC East aint been raisin' hell the last decade (Eagles 2017 NFL Title the exception); however - it is the most competitive NFL division over for the last 16 seasons. No repeat champion in that time span - and the titles are somewhat evenly distributed among the four rivals. But other than the Eagles title run after the 2017 season - no NFC team has been in the conference title game since the 2011 Giants - while three AFC South teams have made it to the title game.
I am just addressing your opinion that the Texans' division titles are not notable accomplishiments.
