That's a massive stretch. Halak has been above average in the playoffs. Playoff hockey is a different animal. To say a guy who is barely an NHL goalie, is as stable as Jaro Halak in net is borderline insane. Not one Islander fan would be comfortable with Berube starting a game in the playoffs if needed. He is an unknown in that aspect, and it is ridiculous to sweep away Halak's playoff experience with Berube's 3 good games this year
I may be mistaken, but I believe Redbull essentially meant that he feels relatively comfortable with Berube in a backup role for the rest of this season, giving Greiss a few games off to rest and hopefully stay healthy and fresh for the playoffs; presumably given the up-and-down season Halak has had.
Now maybe I am wrong, and Redbull can correct me if so, but I do not think he meant that he would necessarily feel comfortable with Berube as the starter in the playoffs, hopefully Greiss proves healthy and capable for that job, just in the limited role for the handful of games Berube will be needed to spell Greiss the rest of the way.
Like I said a few times in this thread, I am thankful that Snow and the Isles finally got smart and opted to keep some additional insurance around in Berube. It was an effective gamble - at least so far.
I have enough scarring to my psyche, with memories of the washed-up Nabokov/Poulin/Nilsson games, to last for the foreseeable future. I am very happy to have depth across the system in goal, with what appears to be quality pro players in the NHL and AHL, combined with a swath of developmental prospects throughout in the lower levels.
