Sets the scale of a normal play: an ordinary gain lands somewhere between 0 and this many yards. It is not a hard cap — a big play multiplies it by the big play factor, and at higher Chaos the deep shots can reach a few times this on their own.
The percentage probability on each play that a sack will occur
The number of yards lost when a sack occurs.
The percentage probability on each play that a big play will occur.
The multiple applied to the yards gained when a big play occurs. For example if the factor is 3 and a big play occurs on a 4 yard play, the player will gain 12 yards.
The percentage probability on each play that a goal line stand will occur. A goal line stand can only occur when a player is within 5 yards of the end zone.
The negative yards when a goal line stand occurs.
The percentage probability on each play that a false start will occur.
The number of yards lost when a false start occurs.
How often the small stuff happens: spin moves, broken tackles, stiff arms, bad snaps. These stack, so one play can be a screen pass with a juke and a broken tackle. At 0 plays have no colour commentary at all.
How wild the play calling gets. Low keeps it on the ground with inside runs and checkdowns; high starts calling deep shots and flea flickers, and opens up the rare stuff — interceptions, fumbles, pick sixes, house calls. It changes how a race feels, not how long it takes.
