That's because the people arguing against the idea of acquiring Bernier generally don't seem to know what in the bloody blue hell they're on about, so they repeatedly quote the same tired stat lines, speak in generalities and create silly, simple-minded narratives based on those stat lines (i.e. 'the Kings are an overall superior defensive team than the Leafs, therefore Bernier's SV% would necessarily drop if he played here instead'.... or, my personal favourite, 'Toskala was also thought of as a back-up with starting upside, therefore we should never bother taking a look at another goalie in the same situation ever again'). Because, as we all know, when the situation is comparable, it doesn't matter who it is, they will inevitably fail because Toskala did, amirite?
