Funny thing about this is, in the 80s the Giants were threatening to move to Tampa and I think many people expected them to bolt. The A's owner put up no opposition to the Giants claiming territorial rights to the rapidly expanding South Bay in order to build a stadium, with the A's owner saying that its great to have 2 teams in the metro area or something to that effect. At the time the A's were possibly the more dominant franchise in the city, or at least on par.
Fast forward to the 2010s after the Giants ended up building a stadium in SF city limits, and the A's were looking to build a stadium in the South Bay and were denied by the Giants due to territorial rights. Now the A's are going to move, giving SF the entire market to themselves.
I know this is a well known issue, I just wanted to mention it because its crazy how avoidable this was.
All that said, I don't understand the relationship between SF and Oakland having never lived there. I understand Oakland has its own identity and all that so its not like "oh well you lost your sports teams, just root for the Giants and 49ers". But it also kind of is long term...they will just be accepted as the sports teams for the entire Bay area eventually right?
