Oakland is only their third home.
The A's have been "rumored to move" longer than the Raiders or Warriors. Their moving to San Jose goes back 15 years., at least.
Oakland is their third time zone!
Fremont, down south. Or Sacramento. Or even out of NorCal entirely. There is zero chance Oakland can scrounge up enough spare change to build them a new ballpark and the Coliseum is a horrible place for baseball.
