Between the Rose Bowl, Collosseum, The Home Depot Center where the Chargers played and the new Rams/Chargers stadium, the NFL could easily do the playoff bubble it in LA.
That's in California though and they'll probably not be able to bubble in it due to the restrictions that are coming down. The 49ers can't practice or play until at least December 21st now due to the restrictions Santa Clara County put in place and are not trying to figure out alternatives. It wouldn't be crazy to see other purple tier counties in CA do the same.
