the significance of the team jerseys that Randy was wearing as he traveled through the panderverse?

For reference: “Omg I’m wearing a Baltimore Ravens shirt now! I hate the Ravens! I don’t know if I can do this. Oh, now it’s the Dolphins! Ah! The Chiefs! Oh it’s the Chiefs!”

How does someone who follows American football interpret those lines? Is there anything to interpret, like are they all bad teams or something?
