The problem with the Chargers is the ownership and the situation in general. The city of San Diego didnt want them to leave and the team didnt want to leave. The owners wanted that LA money and used San Diego's refusal for a new stadium as leverage to move, even though the entire LA community was very vocal about not wanting the Chargers. They'll end up moving again or folding.
Not sure how much truth there is to it, but I saw a "rumor" on social media yesterday that the league is already considering finding a way to move The Chargers back to SD. I'd be shocked if they're in LA for more than a few seasons.
You think the owners get paid again if they move back?
