I like using NFL stats as a cross comparison. I don't necessarily need complete statistical realism, but it helps when making an argument about what positions should do what.
How does it help make an argument when you KNOW there are real, explainable reasons why MFN stats will NEVER resemble NFL stats?
The comments you make about HOW players should play (LBs / OL / etc.) are good information that helps to identify potential issues / fixes. Comparing how players play is helpful.
Comparing stats in MFN to stats in the NFL / NCAA / CFL / Arena League does nothing at all and often leads to a misconception about what the real issues are.
"we need to increase/decrease the RB ability so that league leaders are averaging about 4.9 yards per carry"
When what should be said is:
"RBs need to have the ability to find a hole, make cutbacks, break some tackles; while the OL needs to be able to hold a block: while the DL needs to be able to shed a block; while the LBs need to be able to pursue and tackle, etc.".
Stats in MFN are too misleading.
"Running needs to be made harder because when I play against setherick I'm averaging 10 yards a carry
" (not true, but let's assume it was)....
...while at the same time "Running needs to be made easier because when I play lellow I'm averaging 0.8 yards a carry
Stats in MFN are super
-dependent on the opponent you are playing.
