No one knows that. It is impossible to know when he will cool off. We have seen time after time goalies just come out of nowhere and go on a tear for an extended period of time,, sometimes an entire season, sometimes longer. Dubnyk, Anderson, Smith just to name a few. When you have a goalie playing out of his mind you are supposed to milk it and take full advantage of the opportunity. Sadly, the Jets never really gave Brossoit that opportunity to stay in rhythm by making him the starter. It will always be one of those "what if" moments for this franchise do to stubbornness and politics.
Maybe the playoff pressure will get to Binnington but it didnt look that way in game 1. He was in a zone once again. The odds that he will suddenly regress significantly over the next few games are low. Hope I'm wrong but his record now is 25-5 this year. He is just flat out winning games.
