The keyword here is: PEOPLE. Most notably, people that are not me. It's an organ-shifter of a hit, anyone can see that, but the guy on the receiving end was pretty defenseless and it isn't nearly as freakish as what Clowney did (in case you forgot just how awesome his hit was). Hell, this was a blindside hit you see all the time, only difference is the kid's lid flew off his head. Big hit, but not even in the same league as Clowney.
Oh, and I'd be remiss if I didn't recognize the sportsmanship by the blocker after he wrecked that dude's day. He really showed self-restraint and class by not standing over the poor bastard and taunting him with cries of "Awwww...Did the little baby lose his bonnet?" or something similar.
