Don't care about the excuses others are giving Harrison. He could have signed at atleast 3 other ballclubs outside of this division. There is only one reason he is at the Bengals and that is for revenge.
With that said, it's more important then ever for us to get that O-line together and get the running game going. He will illegally hurt Ben if he gets a chance because he's heart is full of venom now. In my mind, the running game has moved up a half a notch in priority now because Harrison WILL hurt Ben. Legal or not.
