It all appears to be arbitrary at this point.  Like Kansas said, there's been a ton of questionable calls in this league already, and we're only three games in.

There have been much harder hits this season on MLB catchers than on QBs in the NFL.  And even when the catcher gets knocked out or injured, there's rarely a fine or even a reprimand.

Goodell is ruining this league.  How many wishy-washy fascists does it take to screw in a lightbulb?
