Chargers are the best argument for legit curses in the NFL. Even like the Bills Drought era ended when they got a franchise QB.
Chargers went from franchise QB to franchise QB, building what seems like stacked team after stacked team, and they never seem even particularly close to a Super Bowl.
There was that one season the Chargers had the number 1 offense and number 1 defense and didn't make the playoffs. Peak Chargers. Destined for hopeful Octobers and sad Januarys forever.
