Lions-Vikings Game Must Be Reviewed by NFL Officials

First, the refereeing. There were three calls/non-calls in this game that drove me crazy.  The pass interference on Calvin Johnson where there definitely was a pass interference was not called against the Vikings.

The pass interference call would have put the Lions in position to probably get a field goal at least. Then, the fumble that wasn't a fumble. On another play, Calvin Johnson caught the ball and was down, and then the ball was ripped out, and the Vikings recovered.  Detroit challenged the ruling on the field of a fumble but the ruling on the field stood.  Johnson was obviously down and still had possession before the ball ...
