I guess I'm saying with different players it might have worked. The approach and these players don't fit. Castellanos and Moose have a history of production but it wasn't achieved using the approach they took this year. As for why they used that approach, my guess it's an organizational philosophy and Bell's role was to implement it not decide upon it. If the organization wants that approach then the organization needs to provide the players who can pull it off.
It reminds me exactly of Drew Stubbs. He was a talented player with some tools, but he was determined to take a bunch of pitches come heck or high water. He fell behind in the count all the time and was easy pickins for the pitcher after that. His approach didn't match what he was physically capable of doing. This season saw a team filled with Drew Stubbs except without the speed and the decent defense.
