Since You Asked For It - Examining JP's Free Agent Signings

A number of you wanted to evaluate how well JPs free agent signings have performed. To help you out in doing this, here are some stats.

There's two key components to any free agent signing:

  1. How much that free agent earned
  2. How well that free agent performed


Measuring #1 is easy. Just look at his salary.

For #2, I decided to look at a Baseball Prospectus statistic called "Value Over Replacement Player" or VORP. BP defines VORP as:
    Value Over Replacement Player. The number of runs contributed beyond what a replacement-level player would contribute if given the same percentage of team plate appearances.

To put that into context, it usually takes an extra 10-11 runs or so to produce an extra win for the team.

Thus to examine the tradeoff between price and performance, we look at the following things:
  1. 2002SAL, 2003SAL, 2004SAL. The salaries of the players in 2002, 2003, and 2004 if they were with the Jays in those years. Here we use units of $1,000.
  2. TOTSAL: The total salary earned while with the Jays.
  3. 02VORP, 03VORP, 04VORP. Points of VORP earned in each season with the Jays.
  4. TOTVORP: Total VORP earned while with Jays.
  5. V/M$: This is the amount of VORP collected per million dollar of salary. Here higher is better. A 10.0 would indicate the player collected 10 points of VORP for each million dollars earned.
  6. V/EX$: V/M$ is kind of misleading since a replacement level player should collect 0.0 points of VORP but collect $300,000 in salary. So V/EX$ compares VORP to "excess salary" or the salary collected above $300,000. Thus V/EX$ is higher than V/M$

Note that many of the totals for Table II are very misleading, as many of these players only played a fraction of a season with the team, so they would not collect their full 300K.

Also note that in Table I, I assume that all contracts were not insured, so that a player collected his money even while on the DL. This makes some players, like Myers, look like poorer signings than they actually were.

So that's the data. Anyone care to comment on it?
