With Bonds announcing that he will be out for half the year, maybe the entire year, that leaves the Giants roster looking... much like the 2004 Seatle Mariners. If the Giants drop off and tank much like the Mariners in 04 did, this could give the A's a chance to shine.
If the A's get off to a good start and finish better then the pundits think we will (IE: over .500), then I think we have a good shot of reclaiming our fanbase. We'll be THE Baseball team that is actualy winning in the Bay Area. While the Giants are set up to fall once Barry isnt there (which is reality now), the A's are setup to succede dispite losing stars.
This could go a long way for a new stadium.
