Salary vs. Performance

What baseball teams are spending their money well,
and how does it change over the course of the season?

A steep blue line means that the team is doing well for its money, which reflects well on the team's General Manager. A steep red line implies that the team is throwing away money. The thickness of the line is proportional to the team's salary relative to the others.

Drag the date at the top to move through the season. The first few days of the season are omitted because the rankings to (at least) that point are statistically silly. You can also use the arrow keys on the keyboard to move forward or backward one day.
