The Formula

1. Add the sum of all short term acquisitions, all short
term player losses, all short term free agent gains, all
short term free agent losses and all short term
prospects for the season in question.

2. Add the sum of all long term acquisitions, all long
term player losses, all long term free agent gains, all
long term free agent losses, and all long term
prospect losses for the same season. (If a GM
participated in a team formulation draft, he accrues
long term points ((but not short term points)) for the
subsequent season performances of players he drafts
as well. They are tabulated in the same fashion.)
Divide this total by two.

3. The sum of these two steps is the GM rating for the
season.

4. To calculate a general manager’s rating over any
period of seasons, divide the ratings in each category
by the number of seasons and sum the totals. Note:
Except in rare instances where he takes over in mid-
season, a general manager cannot have a long-term
rating in his first full season as a general manager.
Therefore, when calculating a GM’s career rating,
divide his long term scores by the number of seasons
minus one.

5. In cases where a GM leaves an organization,
acquisitions made by that GM continue to count as
part of his residual rating until one of the following
things happens: 1. Players who had been acquired by
the departed GM are re-signed under terms outlined
in the paragraph concerning free agents. 2. The GM
who replaces the departed GM is himself replaced.

The Terms

1. "Acquired" means obtained via trade, sale or via
waiver from another major league team in
exchange for some consideration.

2. "Traded" means sent to another major league
team in a trade, sale or waiver arrangement.

3. "Free Agent" means signed at the expiration of a
previous contract, or following release from such a
contract. Also included in this category are players
re-signed or extended by the same team if those
players are or would be qualified for free agent
eligibility, or if they are signed to a multi-year sign
contract.

5. "Product" means having played the equivalent of
at least one season with the parent team's farm
system. A player is no longer a product once he
attains free agent eligibility, or signs a multi-year
extension.

7. "FA Lost" means those players who left the
organization as free agents or were released and
subsequently played with another major league
team.

8. "Short-term" gain or loss is the BFW or PW gained
or lost as a result of the movement (by any method)
of a particular player either in the season during
which a player is acquired or traded (if the move
occurs in-season), or (if during the off-season) in the
season immediately following.

9. "Long-term" gain represents the BFWs or PWs
generated by a player in any season subsequent to
the season of his acquisition for the duration of his
current contract with the team, or until he attains
free agent leverage, or until he signs a multi-season
contract extension.  

10. Long-term loss is calculated using a sliding
scale of all the BFWs or PWs generated by players
over the first five seasons subsequent to the season
in which short-term loss is calculated. The sliding
scale is as follows: 100 percent of BFW or PW in the
first season of long-term loss, 80 percent in the
second season, 60 percent in the third season, 40
percent in the fourth season, and 20 percent in the
fifth season. Following the fifth season of long-term
loss, no value is accrued.  If the player is reacquired
by the team during that period, calculation of long-
term loss is halted.

11. “Residual rating” is the impact on a team of the
moves made by a former GM. It is calculated on the
same basis as long-term gain and loss.
