49ers in Oakland? York playing the 510 card; ploy of ploys, (but it makes sense)

"49ers consider Oakland."

The headline in Sunday's 'Matier and Ross' report in the Chronicle looks real sexy until you realize that Jed York is going to the '510 option early.

Can you spell "P-L-O-Y?"

Although, ironically, the idea of a shared stadium in the existing Oakland Coliseum, (with about $200 million of improvements) makes a lot of sense, particularly if the A's get a new ballpark in downtown Oakland.
