The main concepts are about Billy Bean, the general manager of the Oakland A's, and the revolutionary techniques of appraising talent and selecting baseball players he and his staff pioneered. Despite having one of the lowest payrolls in all of major league baseball, something like 1/5 the size of the biggest budget teams, Oakland won more games than any other team over a recent four year stretch, though their post season success was lacking. The brilliancy of Billy is his rejection of all typical analytical baseball stats, and the fact that he found better stats to measure talent. His style was largely one of necessity -- the budget he had to work with in Oakland wasn't large enough to get the players everyone else thought were solid. Billy starts off with these huge lists of top prospects, and simply throws away at least half of them right away. Guys he knows Oakland can't pay, high school guys he doesn't think are anywhere near as good as the scouts say, guys who look good but don't have any stats. The main reason for Oakland's recent success is the "big 3" their three great starting pitchers, all of whom were drafted shortly before Billy Bean took over the team. He gets credit for promoting them to the majors and surrounding them with talent to win games, but he obviously had some luck in inheriting those weapons. Since two of them are now gone, traded away before they became free agents and thus became far too expensive for Oakland to afford to keep, 2005 should be the best test yet of Billy Bean's ability to massage a low-pay group of players into a quality baseball team.
This article in a way is similar to the other article based on the question and answer of the confession of Shoeless Joe Jackson. They both involve the concept and importance of money. I feel the game of baseball is based on money instead of pure talent. The White Sox’s were willing to throw the entire world series give up all their hard work for money. The Draft in the article “Trading Desk” is all about the concept of buying players they feel will help them win the series. The fact is that Billy Bean ignored that concept of money and based his decisions on pure instinct and talent and in the end built and amazing team.
