While I hate the Cowboys I DO respect them. Landry in my opinion is one of the best coaches to ever walk a sideline. Lombardi is still the man. BTW Lombardi invented the flex defense. Look at old Packer game film from the 50's. They were using the flex before Landry gave it it's name.
Insofar as the Texans not having won anything yet. Go to the Cowboy's official page and look at their records for their first decade of existence. You'll see some striking simularities between the two clubs. Landry coached the Cowboys to five superbowls (two wins) but their first 8 years they sucked hard and went from sucky to mediocre.
The reason many of us hate the Cowboys is because we grew up having two superbowl wins rubbed in our faces in the 70's while hearing "What'd your Oilers ever win? NUTHIN'!" We also got an earful in the 90s when our team packed up and the Cowboys won three superbowls. And to be quite honest many of us were insulted by the assumtion that many in big D had that we would automatically become defacto Cowboy fans when our team bailed.
I doubt Cincinatti thought that displaced Browns fans would automatically jump on their bandwagon when their team went to Baltimore. I can't speak for all here, but despite my rancor for the Cowboy organization I respect any team capable of making 8 trips to the superbowl and winning five of those. However that being said, simply because I respect something...doesn't mean I have to like it. BTW our ribbing is all in fun we mean no disrespect.
