I think if the Titans had merely worn throwback uniforms one day after the same manner of every other NFL, there would have been no blowback. In fact, it might have been sorta cool.
But the she-tyrant could not be satisfied with that. She had to parade herself around in Oiler regalia at great length and on inappropriate occasions (such as Titans draft day) and apparently compel others to do the same, lest they incur her disfavor (and she being the one with the power to terminate employment). If she set out to be offend (and it's not certain that she did not), she could hardly have arranged things in a worse way.
It looks like she has a very unhealthy, even perverse, obsession with trolling her old social set in Houston. I'm hoping the grandson will not be such an ass.
