Not an easy question. Barring a lights-out from Sorokin really soon, I think the Islanders won't hesitate to use Varlamov as the 1A, which takes Sorokin out of the running for besting the others in wins. That leaves the question of whether you believe Vanecek's usage to date is real. If it is, then Vanecek stands to out-win Petersen given their relative team strength. If not, then Petersen has a decent shot as he seems to be the one of the three who will get the most starts. I think Vanecek is for real and will be given 1A status, or at worst split 50/50. Even with all of the above, I think that Sorokin ends up with the most shutouts, as his talent and team would seem to be the best environment for fostering no goal games. But Vanecek's wins should outpace Sorokin's.
