Joking aside, Cowherd is smart in that he talks about the fan favorites.
He used to bash Tony Romo, because Dallas has a big fan base. Then, he loved Tony Romo, because Dallas has a big fan base. Then, he slammed Dez Bryant, because Dallas has a big fan base. Then, he loved Dez Bryant, because Dallas has a big fan base.
The same goes for the Steelers. Tomlin, BB, AB, Bell (et al) are people he "obsesses" about... because, the Steelers have a big fan base.
