Totally disagree. If Kraft manages to get these charges dropped, that gives Goodell and the other owners a lot less to work with in terms of penalties.
And it would seem like the argument you're making is that Kraft should just plead guilty and say "yeah, I did it" and the league would go easier on him. Please tell me that's not the argument you're making. As far as embarrassment goes, if Kraft is willing to endure it, then who cares? But if you think a guilty plea gets him leniency with the league, you're dreaming.
