The NFL league office wants to avoid having the Oakland Raiders relocate to Las Vegas and the San Diego Chargers moving to Los Angeles.

The league is concerned with the Chargers becoming the Clippers to the Rams' Lakers if they move to Los Angeles. San Diego voters rejected a plan to build a downtown stadium, which could leave the Spanos family with Mission Valley as their best option.

There are also concerns with the Raiders leaving the economic wealth of the Bay Area along with their longtime passionate fan base for Las Vegas.

Mark Davis would likely need a partner to build a new stadium in the Bay Area.
