Nevada,
The key wording is bump... was it a clean bump or was he just clearing the player out of the way. Was it really shoulder to shoulder or was it a swim move? Was it a retaliation for getting beat on a previous play? Was the contact hard enough to be violent conduct? Was it a challenge or just a "take down?" Or if there are girls was it shoulder to shoulder or did she do that unique "chick thing" and put a hip into her which is not a legal move.

The OP asked for things to look for. I mentioned a few. I was neither questioning nor seeking to negate anything you said. I just mentioned, as a humorous side, that my reply was blue and yours was red.
