I am not kidding or exaggerating when I say this, this was probably the best episode of Hard Knocks that HBO has ever made. I also wouldn't be surprised if this is the highest watched episode ever. The beginning was heartbreaking with Philbin talking about his son, there was a lot of great topics during the show and the ending with Chad being cut was something that is hard to describe. Philbin took charge, but you do have to feel a little sad for Chad.
Clearly domestic violence isn't something anyone should condone but I don't feel sad for him at all. Even if the chick is the most annoying person in existence, head-butting your wife is unacceptable. Combine that with Johnson's history of being controversial on the field and that he's on his last legs, the move makes sense to me.
