Mostly true, but when you are always widely mentioned as one of the top 3-5 goalies in the league, he should occasionally steal games. He very rarely does and most games he gives up 4 or more goals while facing minimal shots. For example, in his last 5 starts he has allowed a combined 20 goals and never faced more than 29 shots, many of the times facing as few as 22-23 shots. This is not like in seasons past where he was facing 40-45 shots every night.
If you put Hellebuyck in the Isles net instead of Sorokin I bet we have at least 4-5 more wins. That is the kind of goalie Sorokin is always compared to but he is not playing on that level.
