I am opposed to picketting, but I don't know how to show it

At the very end of the article, when King is talking about Leinart, he mentions that he had a -1 TD/interception ratio. Could somebody please explain to this jackass the definition of ratio? As best as I can understand it, this would seem to me that Leinart played some spectacular defensive back, because that is the only way a QB might be able to get a negative interception...
