Below are listed the YAM2 rankings as of the end of last weekend
(3/6/95).   The explanation of the YAM2 method at the end of the ranking
list has been expanded somewhat for those folks who have had questions
regarding the influence of the ranking factors.

        The YAM2 is an intuitively based simple formula which seeks to
measure accomplishment over the course of the season.   It will not
identify the teams which are currently hot,  but views the season as
a whole.
 
        YAM2 differs from the Rating Percentage Index primarily in its
relationship between Win% and Strength of Schedule.   In YAM2 this is a
multiplicative relationship,  whereas in the RPI it is additive.
 
        YAM2 = (Win%) x (Strength of Sched.)
 
        Strength of schedule is quantified the same way as in RPI:  namely
2 parts Opp% added to 1 part Opp-Opp%.   In this implementation the strength
of schedule is normalized to the value of the stongest schedule (Minnesota
this week).   Also,  as in the RPI,  the head to head games are subtracted
from the records before calculating the Opp% in order to prevent "inverse"
effects on the ranking metric.
 
        YAM2 gives equal *mathematical* weight to Win% and Strength of Schedule.
However,  since Strength of Schedule inherently varies less than Win%,  SOS will
produce less effect than Win% upon the ranking placements (approximately
five positions maximum from experience).
 
        As a property of the multiplicative relationship between Win%
and Strength of Schedule,  YAM2 will not produce "inverse" ranking
effects.   For instance,  it will not raise a ranking if a team goes
to MN and loses two games (except in *very* unusual circumstances:-).
