YARDS PER POINT

TEAM OFF DEF DIFF

SD.ST 11.5 14.5 -3.0

BOISE 13.4 22.8 -9.4

My simple questons is, how to to understand, SHOULD I use this as part of my handicapping, the math calculation. I see that SD ST has a better offense and Boise has a significantly better defence,...thus the number in the sum of the difference, -6.3
Am I to understand that in theory, Boise should be favored by 6.5 ?
What would be a near perfect number or what is an excellent number ? In other words, is there a standard 'perfect' number or is there a number to reference too ? Thanks in advance

Yards per point represents the number of yards a team gains (or allow) for every point scored (or allowed) - on average. It's not meant to do the type of line comparison calculation you're attempting.

If you can project total yards for team in a given game, then you can use YPPT for their offense and opponents defense to translate that to a predicted score. The key of course is to generate an accurate projection for yards gained. (The FoxSheets game estimator projects yards gained for each team.)

The calculation you are attempting is more appropriate for offense/defense points per game averages.

I hope this helps.
