The biggest culprit in my opinion is the lack of moves in the offseason, especially at 2B and Lind platoon partner.
AA gambled in the offseason and lost; he thought he could hope for the best case scenario out of 2B, without considering that other areas, like the bullpen, might get worse, IMO.
To be honest, at this point, I'd almost rather face Shark than a Brad Mills type guy, because at least in brings Lind and Rasmus back into play offensively.
