I have been call an o-linemen snob because my standards for run blocking are high. I prefer an individual block % between 40% and 45% (or higher)!!!
In the IFL, my team KRB % was 42.9% and 47.0% over the last two seasons. And that means the individual KRB % are high for most of my linemen. Of course, you do need big red bars, some chemistry and the right RB(s) to make that happen. The run block bar average for the 5 lineman is over 87.
This is a smash mouth team, BTW.
