Particularly 1B/DH/2B in an 11-to-make-9 scenario...
Always remembering that Beane keeps jobshares going all around the diamond ... Dustin Ackley's position versatility could be Zobrist-like in its value.
Like if they ever had 8 position players they settled on, Dustin Ackley as the 10th man (even getting 550 AB's if he had a .390 OBP) could play LF, RF, a little CF, a lot of 1B, a lot of 2B, and could also play 3B/SS (via Nick Franklin shifting over). With Franklin moving around, Seager playing 3B/2B, Ackley could literally sub in at any defensive spot.
