If KRod pitches lights out with the Brewers, there is no way that Boras lets him accept arbitration. It may be a risk, but its a calculated one and one that should pay off. There is always someone out there willing to give closers a deal. He might not get the blockbuster deal, but if he pitches well he will almost certainly be able to find something better than an arby deal. Unless of course he pitches poorly, but then he would be Type B anyways and you probably don't offer him arby.
