Vikings No Call, Integrity of the Game and the Saints

Integrity of the game will never be confirmed as questionable because human error is accepted collectively and insinuating that something is planned or predetermined isn't.

The league won't adapt certain technologies that would improve the game because it would take "human error" out of it and the shade it provides.

Fact is, if you're playing well enough, human error can be overcome. An ideal example of this in play is ThanksGiving 2013 Ravens vs Steelers. Tomlin gets caught looiking at the jumbotron, doesn't realize he's on the sideline the return is happening on and nearly trips Jacoby Jones arguably stopping a return TD.

The Ravens still won that game despite the human error.
