[net.games.pbm] pbm football -- rules clarification

chuck@dartvax.UUCP (Chuck Simmons) (09/24/85)

Carlo's rules for pbm football need just a little clarification.  As I am
volunteering to moderate this game, I feel justified in clarifying the
rules in any way I wish.  The rules below differ from Carlo by clarifying
how drafting players works; giving rules for trading, releasing and signing
players given the idiosyncracies of the network; and modifying Carlo's
scoring function in very minor ways.

Interest in this game seems quite positive.  Because of the need to publish
detailed rules, and to allow as many people to participate without
handicap, the initial draft will take place on Wednesday, 2 Oct 1985.

Thanks go to Andy Groh for helping me clarify these rules.

My apologies to Carlo if he feels I have abused his game.  This is not my
intention.

Rules for Dugwal Football

1)  Permission to duplicate these rules is given as long as this message
is included.  This game was designed by Carlo Sgro
(...!watmath!watrose!cjsgro or ...!ihnp4!chinet!dagwood) on 12 September
1985 for the enjoyment of readers of net.games.pbm and net.sport.football.
These rules cannot be used for commercial profit without expressed written
consent of the designer, Carlo Sgro.

2)  Overview:  The game is played by an unlimited number of people,
hereinafter known as "owners".  New players may join the game at any time,
though at a slight handicap.  The game is played in weekly installments.
During the first week, a "draft" is held.  (See "drafting" below.)  At the
end of each week, each owner receives a score based on the statistics
obtained by his players during the week.  After this, players are released,
traded, and signed.

The object of the game is to obtain the highest score for each week as well
as for the whole season.

3)  Drafting:  At the beginning of the game owners draft a team of 7
players.  Now, drafting is a little tricky, so read this rule carefully.
Each owner will submit a single list of players to the moderator.  This
list should contain the name and team of each player.  The list should be
sorted in order of how much the owner wants each player.  The list should
_not_ be sorted in alphabetical order, nor should there be a different list
for each position.  Drafting rookies and players who are not in the NFL is
legal, but points will be calculated on actual NFL statistics.

The moderator will place the lists in some pseudo-random order.  After each
draft round, the order of the lists will be reversed.  There will be 7
draft rounds.  By default, the moderator will give an owner the topmost
player on the owner's list which has not yet been drafted.  However, this
well probably not produce great results.  Therefore, each owner may also
submit a _brief and easy to understand_ description of the order in which
players are to be selected.  (Remember that the moderator is not very
bright.  The moderator reserves the right to interpret instructions in
any reasonable way he pleases.)

Clearly we need an example.  Suppose Joe Blow submits the following list:

    marino    dan    dolphins qb
    montana   joe    49ers    qb
    allen     marcus raiders  rb
    clayton   mark   dolphins wr
    dickerson eric   rams     rb
    anderson  gary   eagles   pk
    fouts     dan    chargers qb
    ...

At the same time, Jane Blow (his sister), submits another list preceded by
a few instructions:

    Instructions:  The 1st player chosen for me should be a QB.  The 2nd
    and 3rd players should be 1 RB and 1 WR in either order.  The 4th player
    should be a PK.  The 5th and 6th players should be 1 RB and 1 WR in
    either order.

    marino    dan     dolphins qb
    montana   joe     49ers    qb
    septien   raphael cowboys  pk
    allen     marcus  raiders  rb
    dickerson eric    rams     rb
    solomon   freddy  49ers    wr
    ...

The players that are assigned on each draft round (assuming ladies first)
will be:

        Jane                             Joe
    1.  marino    dan     dolphins qb    montana joe      49ers    qb
    2.  dickerson eric    rams     rb    allen   marcus   raiders  rb
    3.  solomon   freddy  49ers    wr    clayton mark     dolphins wr
    4.  septien   raphael cowboys  pk    gary    anderson eagles   rb
    5.  ...                              fouts   dan      chargers qb

Notice that although Raphael Septien appears 3rd on Jane's draft list, he
was skipped over because of Jane's instructions.  Also notice that Joe has
obtained 2 QBs and 2 RBs by the 5th draft round without picking up a PK.

4) Movement:  owners may change the composition of their teams in three
ways:  releasing players from their team; signing free agents (unowned
players); and trading players with another owner.  At no time may an owner
possess more than 7 players for her team.

Each owner can make one player movement each week.  A player movement is
defined as a trade of one or more players with another owner, or a signing
of a free agent.  Player movements not expended in a week can be saved up
to a limit of 3.  An owner who does not have 7 players after the initial
draft will be given extra player movements up to the limit of three for the
purpose of signing additional players.  (However, the player movements may
be used however the owner sees fit.)

Player movements become official on Wednesday nights.  At the beginning of
the night the moderator will first make any trades that have been
requested; then players will be released; and finally free agents will be
signed.  After this has been done, the moderator will publish a list of
players that have been released, traded, and signed.  The moderator may not
tell anyone about players that will be released until after the signing of
free agents has been performed.

4.1)  Releases:  At any time any owner may "release" a player from her team.
The player becomes unowned and may be signed by another owner.  A release
does not count as a player movement.

4.2)  Trades:  Whenever two owners who each posess a movement point agree,
they may trade players on a 1-for-1 basis.  Each owner must tell the
moderator which players are to be traded.  The trade will not be made until
the moderator has received notification from each player.  Each player
traded counts for one player movement.

4.3)  Signing free agents:  Owners possessing player movements and having
less than 7 players on their team may submit a list of free agents that
they would like to sign.  Free agents will be signed up on each Wednesday
night in a manner similar to the drafting process.  Each free agent signed
counts as one player movement.  New owners (people who do not yet have
teams) may participate in this weekly sign-up.  To do so, they are given
7 player movements.

5)  Scoring:  Scoring is based on the weekly NFL statistics of each player.
For each owner there are 7 subscores:  QB1, QB2, RB1, RB2, WR1, WR2, and
PK.  To obtain these subscores, we examine the performance of each player
on the owner's team for each position.  The highest QB score is assigned to
QB1; the 2nd highest QB score is assigned to QB2; etc.  A single player may
be responsible for more than one subscore.  For example, Joe Montana may be
responsible for the QB1 and RB2 scores.  (However, Joe Montana cannot be
responsible for both the QB1 and QB2 scores.)

An owner's total point value will be determined by the following formula:

    27*qb1 + 6*qb2 + 23*rb1 + 9*rb2 + 13*wr1 + 9*wr2 + 13*pk

Thus your top runningback contributes 23% of your total point value while
your backup receiver contributes only 9%.

The subscores are calculated based on the following formuli:

    qb = (td*10 + %completed*10 + yds/10 - int*5) / 2
    rb = td*10 + carries + yds/5
    wr = td*10 + receps*4 + yds/5
    pk = good_fg*30 - bad_fg*15 + %good_xp

(Note:  These scores differ from Carlo's in essentially 2 manners.  First,
a quarterback that made no tds but threw one interception received negative
points, even if he had a high completion rate and a high number of total
yards.  Secondly, in this model, a place kicker receives points based on
the percentage of extra points made rather than on the absolute number of
extra points.  The reason for this is that a bad place kicker for a good
team will be given many opportunities to kick extra points, and we don't
want to reward the place kicker just for being a member of a good team.

It is our intention that an "average" player will obtain about 500 points
over the course of a year, regardless of whether he is a QB, RB, WR, or PK.

It is our opinion that these formulas are marginally better.  However, you
may think we are complete idiots.  We would be very interested in the
formula used by _The Sporting News_ to compute quarterback ratings.)

Example:  Your team consists of:

Dan Fouts:  19 td, 17 int, 62.5% comp, 3740 yds
      qb = (19*10 + 62.5*10 + 3740/10 - 17*5) / 2
         = (190 + 625 + 374 - 85)/2
         = 552

Dan Marino:  48 td, 17 int, 64.2% comp, 5084 yds
      qb = (480 + 642 + 508.4 - 85) / 2
         = 772.7

Marcus Allen:  275 carries, 1168 yds, 13 td
      rb = 13*10 + 275 + 1168/5
         = 130 + 275 + 233.6
         = 638.6

Mike Pruitt:  163 carries, 506 yds, 6 td
      rb = 60 + 163 + 101.2
         = 324.2

Mark Duper:  71 recepts, 1306 yds, 8 td
      wr = 8*10 + 71*4 + 1306/5
         = 80 + 284 + 261.2
         = 625.2

Cliff Branch:  27 recepts, 401 yds, 0 td
      wr = 0 + 108 + 80.2
         = 188.2

Tony Franklin:  22 good fg, 6 missed fg, 42 good xp, 0 bad xp
      pk = 22*30 - 6*15 + 100
         = 660 - 90 + 100
         = 670

Total score = 27*772.7 + 6*552 +23*638.6 + 9*324.2 + 13*625.2 + 9*188.2
              + 13*670
            = 60311.9

Oops!  This isn't quite right.  This should be:

      qb = (td*10 + %completed/10 + yds/10 - int*5) / 2
      pk = good_fg*30 - bad_fg*15 + %good_xp/20

Thus in a "typical" game, a quaterback with 2 tds, 60% completion,
300 yds, and an interception would score

    (2*10 + 60/10 + 300/10 - 5) / 2
    = (20 + 6 + 30 - 5) / 2
    = 51/2 = 25.5

A "typical" place kicker might get 2 field goals, miss one, and
make 100% of the extra points for a score of:

    2*30 - 15 + 100/20
    = 60 - 15 + 5
    = 50
