Mahanga / Wikimedia CommonsThe Dallas Cowboys are not very good. They have not been very good in some time. It's true that they aren't dreadful, and have not been "dreadful" in some time. But they are the worst kind of team for any fan--highly unpredictable, capable of both brilliance and stupidity. I was with the Cowboys during 1-15 and 3-13. There was some serenity in sucking so badly, some security in being not simply the worst team in football, but one of the worst in history. You knew what you were. There would be no nail-biters. You hoped to beat the Redskins and then you moved on with your life.
