Again, I get the sentiment, but the Rays always seem to get pretty big returns on their players, and they're still able to hold onto them far longer than the A's do. The Rays have extended Moore, they've extended Zobrist, they've extended Longoria. Shields was there for a long time, Price was there for a while. Someone who's grown up as a Rays fan over the last several years will recognize a lot of the guys there as franchise players.
I know the A's are in a limited market, but there are other teams with similar handicaps, and yet nobody does things the way the A's do. And yeah that's probably what appeals to a wide majority of people about the A's FO, but that's also probably why their fans are jaded.
Like I said, I do think it'll eventually turn out well for them, as it always does, but losing five all stars in one year, and every single one of them to trades as well, it's gotta hurt the people that follow that team, no matter how optimistic they can be.
