No, the point is that if you're going to cry foul, you need to actually be able to back it up with logic, motivations, and real evidence.
As for the 'evidence' that you provided, the ownership transaction passed only because it was approved by 24+ owners, so saying that the league office favored the Steelers is just idiotic. If the other teams had any problem with it, they could have rejected it. They didn't, because they realized that allowing both Rooney brothers to be recognized as one person is a complete non-issue.
Recap: the 'exception' that they made was allowing the two Rooney brothers to count as one person. THE HORROR. Note: the Packers don't meet this 'requirement' either, so it's not like the Steelers are unique here. If that's the best evidence that you can find that the league favors the Steelers, then my point's pretty much proven.
Whatever; I'm not exactly surprised that a pretty simple, A-to-B-to-C argument is once again flying right over your head.
