Ok, let's look at a few things
1) McCoy was also waaay out of the box. However, he was behind the line of scrimmage. The ball had left his fingertips, and he had come down from a jump. Given that time, that might be a roughing the passer. But, we'll ignore that for the sake that Harrison had commited to that hit before the ball was off
2) McCoy was helpless. He jumped up in the air to see what was going on with his receiver, and keep the ball out of Harrison's hands, in case he tried to deflect it. He barely came down when he took the hit.
3) As I said before... Harrison wasn't committing to tackling the QB, he was committing to HAMMERING him. He tilted his shoulders, and jumped into him head first. Look at where his helmet is. It's not "grazing his helmet after bouncing off his chest", he's out and out smashing into him. It would be a decent hit and all too, if he had lowered his shoulders further, and put his arms out to grasp him. He didn't do any of that. He KNOWS better. He didn't jump into him, holding his arms out. Watch his arms in the play, they're practically flailing in the wind. He jumped upward, and into McCoy. McCoy didn't even know his own name after the hit!
I don't know what you guys are smoking, but I don't care what player on what team would commit this kind of hit. That's a big hit, and as I've pointed out, the guy isn't trying to just tackle him. Watch his stature and you'd clearly see it's not your typical tackle. If you don't believe me, instead of watching some Youtube vid of somebody recording the game with a camcorder on a TV where you can't see shit, look at the link Steve posted, or look at this link

You see that this wasn't a soft hit, and as are mentioned in all the press bits that Harrison is well-known for these kinds of hits
As for anyone else,... Any other player in the league that has given this many hard shots would've been suspended several times by now. Your Steelers get away with a lot of shit too, you know
To answer the question about running backs... Running backs tilt for momentum to run. And defensive players know that they can't just drop their shoulders to hit them with their heads... They reach their arms around them, wrap them up, and pull them down
That is called a T-A-C-K-L-E
Often, defensive players tilt their heads to hit for the same reason, placing their helmets at the chest, NOT THE HELMET! If they see someone openly running, they'll tilt their head to the side of their chest, and put their shoulder to their chest, using their arms to narrow their escape chances
Believe me people, we're not talking about a bunch of school-yard ball, where some don't know much about the rules while others make the rules. We're talking about a bunch of PRO ATHELETES, who have played the game longer than some of you have been watching, and they've been playing it BY THE RULES. The defense LEARNS how to tackle properly, and not leading on with the head the way that Harrison depicted
Now that I've reiterated all of that, I'd be willing to bet $10 that a bunch of you would probably start yelling and screaming if you saw Ben laid out like that, and moaning about how a 1-game suspension is deserved, if not more. When it comes to hits like this, it doesn't matter who's helmet is on, what colors are on, and who the player behind the mask is. There's an obvious right from wrong here. McCoy had his bell rung pretty badly, and Harrison did something no one person should do against a another player. Even not liking the Steelers, that's something I have to say about any player that makes a hit like that. That was just wrong
