Stupid Statistics

I love statistics, but I have come across a few instances where subjectivity plays to big of a factor into certain stats.

Stat #1
The Bears rank 14th this year in pass blocking on the O-Line according to footballoutsiders.com

What!? This can not be right. This offense line is fucking garbage! I think that because Jay is able to get the ball off in time and gets tackled after he throws the ball that the offensive line doesn't charged with the shit it should

Stat #2
There is a stat on pro-football reference called "Big Games"

Here's what defines a big game 300 yards passing, 100 yards rushing or receiving, or 4 TDs- what arbitrary shit is this!?
