And that's great, however, the agreement was for St. Louis to ensure they had an upper echelon facility in the NFL, that was the agreement and Stan spoke about that the day they announced the move. Even with the new stadium proposal, it did not put St. Louis in the top 5 stadiums, which was factored in to be competitive, now we can debate that topic, but if they had made those improvements to the Convention Center, it would have been in that top percentile.
In the end, Stan wanted to move as like John Shaw in the 90's that oversaw expansion and realized the opportunity, ESK oversaw the Los Angeles committee and understood what it would take to have a football team in Los Angeles and he felt he was the guy to get it done.
As to the Chargers, I believe Mexico City is in their future. Logistics not an issue and a fan base like no other, however, that's down the road IMHO.
