What PA said. I don't think you have to hit someone up that high to get a boarding penalty. But I think if you're sticking your butt out like that you should expect to get pushed. I'm fine with them not calling it boarding, but I feel like I've seen lesser pushes get the gate.
We really don't though. There is SOOOOO much more going on than we could ever hope to hear about. There is sooo much stuff that teams and reporters and players keep quiet. Those examples are, like, the tip of the iceberg.
