But doesn't look like a dirty, hard, or malicious hit at all. In fact, you can't even tell which defender he is. THe WR gets dragged down by one guy and then kind of falls into the other defender running backwards.

It must have been preventable if they're kicking him off the team over it, but from that angle, it's hard to judge.

My guess is he wouldn't have made the team anyway and they're either just sending a message or creating a spot for someone else.
