I don't think you can deny that he seems to go for those hits at times the players are vulnerable. By vulnerable, I don't mean they are facing the boards, or being hit from a blind angle. Rather, he hits them right when they are looking down to collect a pass, or trying to fish it away from the boards.
Yes, I know the common argument is that they need to keep their head up, but that's a bit of a disingenuous comment(and your statement that they lack hockey IQ and need to go back to beer leagues is simply an ignorant comment), since every player looks down momentarily when they are collecting a pass, or pulling the puck away from the boards. It's a play that happens many, many times over the course of a game.
As far as the rules are concerned, is this really a bad hit? No. It's perfectly legal. He's hitting them just as they are coming into possession of the puck, and are not legal to be hit. But it really shouldn't be that surprising that people see it as a predatory hit, especially when he leaps into it the way he does. It's the kind of hit that is legal, but only just. It's also, very likely, one of the reasons why there have been so many threads regarding his hits. Legal as they may be, they're kind of, well, dickish.
