This whole thing reminds me of the old adage of the two swimmers being chased by a shark. You don't have to outrace the shark, you just have to outrace the other guy.
There are currently a bunch of other teams in a lot more danger of being bought and/or moved than this one. San Diego, St. Louis, Jacksonville, to name three.
By the time a buyer gets around to being able to move this team, there probably won't be any place left to move it. In other words, we're going to outrace the other guys.
