Prob b/c the league's whatbit is broken.
Anyway, saw the NFL fired a ref this week - a sign that they are willing to impose some accountability (or the illusion of it at least) on their refs.
I've never bought into the idea that a league would tinker with games like today's, however I could see all the major sports leagues tinkering a bit when it comes to keeping small market teams out of championship games/series if they're going up against a big market team in the semis - however, sometimes I wonder if even that is far fetched. Think of the number of people who'd have to be in on that scheme and keep their lips sealed for decades after. The credibility risk wouldn't nearly be worth the revenues from improved ratings in a game or two.
So yea, I basically just chalk it up to utter incompetence.
