The Bills won’t be moving to Los Angeles. But someone will. Fairly soon.

As the 20th anniversary of the NFL’s departure from Los Angeles, the NFL seems closer than ever to returning. Per a league source, the current plan is that the NFL will send one or two teams back to Los Angeles within the next 12 to 24 months.

The timeline would include a team announcing its intention to move in the 2015 or 2016 offseason, with arrangements to play at the Rose Bowl or the L.A. Coliseum pending the construction of a new stadium. Possible sites for a venue in L.A. include the AEG project at L.A. Live in downtown, the land purchased recently by Rams owner Stan Kroenke at Hollywood Park, Chavez Ravine, and a couple of locations that have not yet been publicly disclosed. Ed Roski’s shovel-ready site at City of Industry is not regarded as a viable destination.

Currently, the universe of teams that may relocate consists of three: the Rams, Raiders, and Chargers. The Raiders’ current lease expires after the 2014 season. The Rams can exit without penalty after each season. The Chargers can leave by paying a relocation fee that shrinks every year.

All three teams previously played in Los Angeles. The Rams and Raiders left after the 1994 season. The Chargers played there in 1960, before moving to San Diego the next year.
