Interesting. @AdamJT13 may be able to clarify if this is true or not because I believe this is actually an incorrect interpretation of stats listed on NFL for defensive penalties. At least that's what I gathered from the old thread discussion about it
That is amazing and you are right about the offensive penalties BP.
They have been killers. I know there is statistical information on what one holding penalty does to the potential for points on a drive - it's pretty brutal.
