In the story, Lewis thinks of the team as the underdogs.
The A's had not been relevant in the league in the years before 2002 but that season changed everything.
Some big moments of the season that are described in the story are the team's record 20 game winning streak, the trading of their star player Jason Giambi and recovering from that, and the team's playoff berth.
The main idea of the book is to show people how Billy Beane basically changed the way of management and made it work.
It also shows how much can happen when a team comes together as one and all players have their minds set on one goal, in this stories case, the goal is making the playoffs.
My favorite part in the book is when Scott Hatteberg, an underlooked player by the league, hit a walk-off home run to give the Oakland Athletics their 20th straight win in a crucial part of the season.
At this part, Lewis said he had never had more goosebumps in his life after that homerun.
Overall, the book left an impression of willingness on me. It showed how one team could go from being irrelevant to the talk of the league. It also showed that when you set your mind on a goal and work for that goal, your reward can be great.
