Well I agree with much of this. It seems we are judging the person and not the action. Plenty of very decent people do / act in very bad ways, but that doesn't make what they did any less serious. I also don't buy into the outcome as a measure of culpability. So what if he wasn't hurt, the action that is objectionable is pushing someone simply because they are in your way. Whether that person falls into a pile of feathers/pillows or a pile of broken glass is irrelevant to the infraction. It's as silly as saying it's ok to fire a gun through your front door every time someone rings the doorbell. Sure you may often miss hitting anything, but is it reasonable to do that? Is it only unreasonable when someone gets hit? No, it's the initial act that is unreasonable.
This is an NFL game where 90%+ of their revenue is based on televising the game to as large an audience as possible including through the use of live video and photo images. That package of entertainment has allowed the owners and players to enjoy record revenues and salaries. While the players may be the stars of this production, all the associated personnel are the various support staff that make their success possible. I don't see this as any different than Christian Bale or any other actor going off on the staff during a filming, except instead of a verbal confrontation it was physical. It really does make the star look like an ass, but there are always going to be a vocal group who support the star. As then I expect the Studio/NFL to just ignore it and hope the situation dies.
