I’ve created a system that ranks NFL teams from best to worst. To do this I calculated seven different statistic and measured how they related to winning. I did these calculations for every game, then found the overall average for a game. I then went back and compared every game to this average, and found win/losses based on being above or below average. Games where teams played above the NFL average on the seven statistics had the following winning %.
Stat.......... NFL Ave ...........Off W% .........Def W% ..........W% Off & Def
DSR........... 69.1% ............66.5% ...........65.4% ............89.14%
ANPY/A ......5.338 ..............70.3% ...........70.7% ............89.10%
Turnovers .....1.76 .............67.8% ............67.5%............ 82.5%
YDS/Drive ....28.36 ............63.2% ...........63.6% ............81.5%
TOP/Drive ......2.77 ............65.4% ...........65.3% ............79.6%
Yds/Play ........5.09 .............62.2% ..........61.6% ............77.4%
FD/Drive .......1.62 .............61.0% ..........61.2% ............76.4%
3rd&4thdw .....39.1% .........62.6% ..........61.8% ............75.11%
The next step is what I need help with. I would like to combine these 7 statistics into a single number for each teams’ offense and defense. Ideally, I would like each stat weighted based on the winning % above.
Here are the statistics for the Detroit Lions Offense:
DSR........................... 61.29%
ANPY/A ........................3.45
Turnovers Per Gm .........2.24
Yds/Drive ...................22.41
TOP/Drive ....................2.12
Yds/Play ......................3.95
FD/Drive .....................1.34
3rd & 4th Dwn ............23.4%
Any ideas?
Thanks,
Randy
