Dave Fleming at Bill James Online makes the case for Buster Posey as the best player of his generation. He also makes a great comparison of Posey to Mickey Cochrane:

Their other commonality – the other trait the two men share – is that both players were winners.

Cochrane played in three World Series with the Athletics, and then found himself fire-saled to Detroit. He immediately led the moribund Tigers franchise to consecutive World Series appearances as catcher-manager. He collected three championships over a short playing career. 

And before he had turned twenty-eight, Posey had matched him on the rings. Buster didn’t make it all the way back this year, but he pulled two other Giants squads into the playoffs, including the Cinderella team that is his last.

My dad grew up a Yankees fan and loved Bill Dickey, but he thought Cochrane was the best catcher of the ERA.
