The New York Giants and New York Jets, who already share a stadium in the Meadowlands, have joined forces to privately finance what will be the most expensive sports stadium in U.S. history.
Now the NFL is urging the Oakland Raiders and the San Francisco 49ers to share a stadium. The owners of the Giants and Jets have also said that they believe building a new stadium to share would be in the best interests of the two Bay Area football teams.
Formal discussions have not yet begun between the Raiders and 49ers, but the Niners plan to expand their scope for a new stadium.
