Look at the tweet I just posted. It's hard to watch.
It has nothing to do with the stadium the 49ers play in, and they are a 6 hour drive or so away which means they have to incur the cost of a hotel, plus the gas and additional food. So it's not cheaper.
The Cowboys training in the area doesn't mean much.
What about the other fans that pack that stadium when their team comes to town? Why are there THAT many tickets available?
Fans not showing up after a team went to the playoffs after an 11 win season and then a Super Bowl after a 13 win season can only mean one thing.
There are in fact not enough Rams fans to fill the stadium. After 3 full seasons and several games into the 4 season I think it's safe to say LA doesn't care very much about the Rams.
