Need help with reading a chart, anyone?

Mods please erase this if it is inappropriate, with my apologies. I was looking around the website and I came across this chart that I am having some trouble figuring out how to read it, does LEA stand for leader? or does anyone know a better site to get this kind of information? I assume this is a pretty good piece of information to have but I just might not be looking at it right. because I would assume the leader for the defense and offense would be the same numbers but that is not the case.

Again sorry if this is not supposed to be posted.

LEA probably stands for league

Well either way it is confusing because you would think that if its vs the league the numbers would be the same correct?

Like for example
GB OFF /vs. Lea/ MIN OFF/ vs. Lea
Yards 313.0/ 95 / 317.3 / 96

the LEA category is the % of the league average. For example GB is averaging 313 yds per game on offense which is 96 % of the league average at the time they put up this chart. Where as Min was at 126 in regards to rushing yards per game because they are averaging 125% of the league average in rushing yards.

Does that make sense?
