I lived in LA when the Rams and Raiders were both in town. Neither team could draw a crowd. The Raiders hosted the AFC Championship game one year and it was blacked out locally because the Colosseum was half empty. Having witnessed the dearth of interest then makes me question why an owner would want to move a team there - aside from leveraging a new stadium deal where they are now.
If you check the stats, attendance for the Raiders was better in Los Angeles than the long term average after they moved back to Oakland. Some of the crowds in that dump they call the Oakland Mausoleum in recent years have been the worst since the early AFL days before Al Davis took over.
As for the Rams, dear old Georgia did nothing to field a competitive team and never did any community relations in the OC to boost attendance. Fans in St Louis have pretty much given up on the team after the Kurt Warner years too. Of course it didn’t matter because for years the city agreed to buy up all the unsold tickets to get the team to move there in the first place.
Hay wait! Wasn't that also in Inglewatts???
