Non-Bengals fans complained, and complained, and complained when it became known that HBO selected the Cincinnati Bengals to be this year's feature on Hard Knocks. Yet, through two episodes this year, the Bengals have blown last year's feature, the Dallas Cowboys, out of the water. Joe Reedy Tweets that "Ratings for first two shows of Hard Knocks up 44 percent compared to last year."
So either people are complaining a lot about the Bengals, and still watching them. Or the Bengals are more popular than the Dallas Cowboys.
