When it comes to hosting the All-Star Game, Wrigley Field has effectively become what Los Angeles used to be for the NFL. For several years prior to the Rams and Chargers moving (back) to the City of Angels, keeping the city devoid of a team allowed other owners to threaten to move in order to get big tax breaks and/or public funding for new stadiums in their current cities. In similar fashion, Wrigley keeps being mentioned as a possible host for the Midsummer Classic only to see other cities land the event.
This goes all the way back to 2016, when the presumption was that the Cubs would be prioritized following the completion of the 1060 Project in 2018.
