It's so easy for a fan to criticize the play calling, but in reality they have no clue what they are talking about.  They don't watch hours and hours of the opponent's game film, they don't sit in on coaches' meetings where opponents' strengths and weaknesses are discussed, they don't develop a list of plays that they think will work based on all of that, and most importantly of all, they have no clue what play was actually called- what all 11 guys were supposed to be doing and why, or whether the QB changed the play at the line of scrimmage and why he did that.  

That's why when I read people criticizing the play calling, I roll my eyes, because it is so ridiculous for a fan to think they know anything about the subject.

All the fans know is, it worked so it's a good play call, or it didn't work so it's a bad play call.
