A's to New Orleans
In 1978, and again in 1979, Charlie Finley tried to move the A's to New Orleans, but the City of Oakland and Alameda County wouldn't let them out of their lease. In 1980, Charlie went through a divorce, and he had to sell the team.
He was going to sell it to oilman Marvin Davis, who was going to move it to Denver, but since the Raiders were threatening to leave, Oakland didn't want to let both teams leave, and wouldn't let them out of their lease, so he sold it to Walter Haas, Jr, President of Levi Strauss & Co. and a local buyer who kept it in Oakland.
If he would have gone through a divorce two years earlier, with the same conditions (and he still had to sell), maybe some New Orleans group with the money to deal with their lease in Oakland could have bought the team from Finley, moved them to New Orleans, and re-named them the Blues or something like that.
