"I should expect SB LIII to have the lowest ratings in History, right?"
What would be the reason this game even makes it to top 10 most watched Super Bowls in History? The LA Market? Brady's fan base? The beautiful Mercedes Benz stadium in ATL? Sure.
But with all the foulness surrounding the NFL, Mr. Goodell, horrible officiating, social injustice & inequality, the gov't shutdown, NFL game protests nation and worldwide, the worst administration in the history of this country, why would you even still be interested?
