The problem with Moneyball as an analogy for web software development is that software development is not a game with a finite pie outcome model, i.e. there isn't a winner for every loser or vice versa.

For web software development there isn't even a clear way to determine winners - e.g. market share or brand awareness may trump revenue as a measure of success depending on the purpose for which web development is undertaken.
