There is no way that the Dodgers could be forced to move, considering they own Dodger Stadium outright and the NFL would have no standing to force them to abandon the location.
Well that's a relief.
The only arrangement that could work out here is if the NFL team rented use of the stadium from Guggenheim Partners, and even that comes with its own set of hurdles, like converting it from a Saturday baseball game to a Sunday football stadium.
I think it'd be BETTER to demolish the stadium than do that. Remember what Angel Stadium looked like in the 80's?
