The Red Sox have done very well in exploiting undervalued markets. Granted, they also have the payroll to sign stars, but many of their bench players and relievers have come cheap. Ortiz, Casey, Cora, Crisp, Loretta, Bellhorn, Hinske, Kielty, Millar, Kapler, Pokey Reese, to name a few. For the most part these were players rejected by their previous teams, or they came cheap. And while they weren't all high OBP guys, the Red Sox correctly recognized they each were strong in one or two particular areas, so if use judiciously could be a valuable contributor to the team. For me that's the central lesson to Moneyball; figuring how to maximize your return without just throwing millions at every problem.
