**Computing a hypothetical per
game offensive line efficiency**

Our hypothetical measure is a function of a
team's passing efficiency rating, its rushing yards per carry, its rushing
touchdowns and its offensive line's penalty yards. That is,

OLE = PEO + YPC * X + RT * Y - OLPY - 5 * SA

Where PEO = pass-efficiency offense; YPC = yards per carry; x
and y = normalizing numbers; RT = rushing touchdowns; OLPY = offensive line penalty yards;
SA = Sacks Allowed

UW Offensive line efficiency = 103.49 + 3.6*20.57 + 1*5.09 - 0 - 5 = 177.63

UH Offensive line efficiency = 93.3 +
4.0*20.57 + 1*5.09 - 10 - 15 = 155.58

(*) The normalizing numbers X=20.57 and Y=5.09
were chosen so that YPC plus RT would be
equivalent to a Passing Efficiency Rating of 100. X and Y are the averages for
the Pac-12 stats involving YPC (X = 90/4.375) and RT (Y = 10/1.96) for the 2013
season. The numbers 90 and 10 were chosen so that YPC would have more weight in
the computation than RT; the numbers 4.375 and 1.96 are the Pac-12 averages for
YPC and RT. To guard against a meaningless
rating resulting from a limited number of carries, the normalizing number x
needs to be restricted. For one, if the number of carries
is less than z then set x=1, with the value of z yet to be determined. Alternatively, the
value of the factor ypc * x could be controlled in a similar way to the limits placed on the
NFL's passer rating computation.

More specifically, the equation for OLE is a function of 10 metrics:

Pass attempts (PA)

Pass completions (PC)

Yards passing (TY)

Number of passing touchdowns (TD)

Number of interceptions (I)

Yards per carry (YPC; sack yardage figures into the calculation)

Rushing
touchdowns (RT)

Offensive line penalty yards. (OLPY)

Sacks Allowed
(SA)

The values for x and y (Pac-12 averages for the 2013 season)

The complete equation is as follows:

OLE =
(TY*8.4+PC*100+TD*330-I*200)/PA + YPC * X + RT * Y - OLPY - 5 * SA
