I'm just extrapolating here, but I believe what he is implying is: The Nationals were loved by stat nerds last year, but they couldn't win it all because Jonathan Papelbon was a cancer. So, though you nerds may love Papelbon because of his stats, he isn't a winner in my book because of his presence. That is why the Nationals didn't win it last year. The best part is how he assumes that people that use sabermetrics are robots who automatically can't use common sense to tell that someone's a "cancer." The GM is too caught up researching the deep abyss of fangraphs.com to see the headlines or hear the scouts warning you that Papelbon choked out the MVP.
