According to Daniel Kaplan of the Sports Business Journal (subscription required), the NFL and its owners have settled on a Los Angeles relocation fee of at least $500 million dollars, with the possibility that it could go as high as $600 million. Some speculation last year indicated the relocation fee would be at least $250 million, while recent speculation indicated it could be as high as $1 billion.
By any measure, this is a ton of money. As Jill Lieber Steeg pointed out in this tweet:
