The perception won't ever change. People get comfortable with ignorant uninformed opinions, and the fact that a good portion of the country is literally asleep when west coast Night games are finishing, means they'll literally never know the difference.
The Dodgers have led MLB in attendance for at least a decade, the Los Angeles region....multiple times a year can fill 2 different stadiums with 80K plus for college football games, on the same Saturday, I mean the Lakers at Staples Center speaks for itself.... as did Showtime era at the Forum.....the Lakers current local cable tv contract is worth more than some NFL team's entire valuation....
the facts have always contradicted the perception, but again, people get comfortable in their perception.
As far as the Coliseum.... I mean anyone who was there for the Chiefs Monday night game.....the Cowboys playoff game.... the Vikings Monday night game ... experienced a Coliseum that was as loud as it's ever been in it's almost century long history. I mean the Coliseum is as cavernous an open air stadium as exists, so a dome small enough to fit 2 domes inside the coliseum may sound louder, but the reality is the Coliseum on multiple national games showed the country that...to quote Joe Buck, the support of the Rams in Los Angeles is just fine.
SSL and ticket sales at SoFi have gone great, and the Los Angeles Rams will have a great home field advantage in the best stadium in the world
