I'll agree with all of them except for the Michigan one. Other than the fact you are seeing that through Maize and Blue glasses, I'm not sure how that is not targeting. It's a crown of the helmet hit to a defenseless player to the side of the head/under the chin. That's the exact hit the rules makers are trying to get out of the game.
Didn't you just get done saying that incidental helmet contact is no longer a foul, because that's what it looks like to me. Calls like that are why I can't figure out for the life of me why you'd want something like that out of the game. The first two I mentioned, absolutely good call. That's where you're looking at breaking your neck or even killing someone. But incidental contact/hit under the chin (which is what I and everybody else in my playing days, which weren't even that long ago were coached to do instead of going for the helmet) that's the gray area I've got a problem with.
Now admittedly it's worse at other levels. In the Arena Football League, jumping offsides twice in a game is a fifteen-yard penalty, and the third is an ejection. Did that reduce the number of offsides penalties? Sure. But can a reasonable person logically conclude that being drawn offsides warrants the walk of shame and sitting in the locker room the rest of the game? (Another reason I think a player DQd for targeting should at least be allowed to remain on the sideline).
I guess it reminds me of checking from behind in NCAA hockey (Sorry, I'm a Canadian, and primarily a hockey guy

) where the NCAA decided to instruct officials ten years ago that regardless of the written rule, any simple boarding/roughing/interference involving the boards is to be called CFB, five and game. The result: at least two game misconducts a night. Where instead of this (what CFB actually is):

https://m.youtube.com/watch?v=AfKTe2EhsQUSo where does it leave us? I honestly think it boils down to a debate of whether we're to be more of referees or babysitters. I tend to think/want my job to be more of judging complete vs incomplete, touchdown vs out of bounds, rather than whether or not a celebration was excessive or telling a kid to watch his language. I want to have as minimal an impact on the outcome as possible. As Chief Justice John Roberts said in his confirmation hearing, "My job is to call balls and strokes, not to pitch or bat. Nobody goes to a ballgame to see the umpire." Just as it should be in the legal world, it should be on the field. But I do feel that we're being asked to take more and more of a cause of the outcome of the game as time goes on.
