I'd prefer switching it up every year to keep things fresh. Eash season is a new storyline.
Listen, this is a team of mainly black men. Black men enjoy rap music, usually. Drew, the white guy that is leading a group of big black guys. incorporated a rap song into a chant. Why? Because it's in hopes of getting the black guys ready to eat someones face. Once again black guys love rap, so they love this chant. Smart move. It's sciene.
