    Actually, I find one of the major mistakes employed by those using RE tables is the assumption that the situation at hand involves “average” players on a team that is scoring an “average” number of runs.  In the RE explanation you provide, this is what is written:

    There are a few major points to keep in mind:
    Game state matrices (runs or winning) are derived empirically from multiple seasons of data.All players and teams are assumed to be average. According to the matrix, at 0-0, nobody out and nobody on, the worst team in the game will have a 50% chance of beating the best team.This provides a baseline with which players and teams can be evaluated. Outperforming the game state means a team is above average, underperforming means the opposite.The transition between game states can yield average run and out values of any given event (linear weights). This is, strictly speaking, a link of a Markov chain.

    Personally, I don’t know how anyone can conclude that, at this particular point in time, the ’12 version of the Pirates are “average” in the run scoring department.  I wholly reject the idea that a RE chart has any application to this particular team.  Further, as identified above, the chart is not meant to be a predictive tool.  It anticipates that there will be teams that don’t perform in conformance with the chart.  While it may be interesting to have a baseline to measure teams’ performances against one another, it is a misapplication of the table to use it to conclude that Hurdle cost the Pirates runs.
