If the NFL were to return to Los Angeles by 2013, there would only one team that would be able to pull it off:
The Rams can’t leave St. Louis at the earliest until after the 2014 season. The Jaguars must demonstrate three straight years of losses before being able to exit Jacksonville. The Raiders’ lease situation is irrelevant, because (as we’ve previously reported) the league won’t allow them to move to L.A. unless Mark Davis sells controlling interest in the team. – Pro Football Talk
A recent memo that was sent out by Commissioner Goodell to the rest of the league outlined the requirements in order to make a move happen. The Chargers would be able to meet all the requirements that were set out by Goodell.
There is also the mayoral candidate race in town where both the leading candidates do not support using public money for a possible new Chargers stadium.
2013? Definitely a possibility. Enjoy the team in San Diego while you can, we don’t know how much longer they will be around. I sure like the sound of Los Angeles Rams though!
