Makes you think what? I've consistently argued against this evolution of the handball rule over the years. Seem to remember a handball from Milner against Roma last season that was nowhere near a penalty as well, come to think of it.
I have no problem with Kuipers giving it, since it's the rule and at least I'm happy it's indeed applied consistently, but I simply don't agree with the rule. That picture above from Rose doesn't tell half the tale, you can't pinpoint such an action in a picture. And you can't possibly say what's a natural or unnatural position if you're trying to block a ball, what defending is all about after all. "He shouldn't go in like that because he risks giving away a penalty" is what will kill proper defending over time, and I hate to read things like that.
