With someone like McKenzie you really have to look at exactly what he says. Did he say flatly the Sabres are zeroed in on Bylsma and aren't conducting a search? If so, he would absolutely not say that without some sources, and at the (inter)national level he's the most connected reporter in the sport. If what he said has any element of speculation then it's a well-connected man making an educated guess. These are completely different things. The former one should assume is accurate unless and until proven otherwise. The latter is something Bob, like everyone else, often gets wrong.
