Clarifying using concept of competitive advantage; goal of manager is maximization of efficiency... three players; Billy, Brad, and Ben Billy walks 35 times per two-fifty at bats, Brad hits 25 homeruns per two-fifty at bats, Ben steals 15 bases per two-fifty at bats... Billy has a competitive advantage in patience, Brad has a competitive advantage in homeruns, Ben has a competitive advantage in steals. Since the goal of the manager is to succeed by employing the most strategically favorable design schemes; the manager has an incentive to bat Ben first, Billy second and Brad third, in order for (t)his lineup to score the most runs possible... Now apply toward teams seeking out certain players on the basis of intrinsic vacancies; a team without a specialized base stealer is willing to pay more for him than another team with one; a team without a specialized homerun hitter is willing to pay more for him than another team with one; a team without a specialized batting eye is willing to pay more for him than another team with one... Realizing the vacancies of the Mets, the Yankees could go ahead and sign ---Ben--- if the Mets need a base stealer; ... realizing the vacancies of the Mets, the Yankees could go ahead and sign ---Brad--- if the Mets need a homerun hitter; ... realizing the vacancies of the Mets, the Yankees could go ahead and sign ---Billy--- if the Mets need a batting eye... Therefore, team A (ie. Yankees) secures their chances of outcompeting team B (eg. Mets) by depriving them of these acquisitions.
