Who said anything abut lumbering sluggers? I think his strategy is to have players like Greene, Torkelson, Carpenter, McGonigle, Clark, etc actually being good hitters and not relying on McKinstry, Kreidler and Ibanez to be working the strike zone and being versatile for 400 at bats.
I don't think what they did last year is a big part of the strategy at all. That is unlikely to happen again. Some of the elements they employed during that period might be used as fillers, but it's not a strategy for sustained success. Talent is still whats going to win the most games.
