The arrangement seems to be working for both goalies, who are sharing the load instead of shouldering it.
"We're both playing well and it gives us a decent amount of rest and time to work with the goalie coaches and stay sharp that way," Greiss said. "We play enough games back and forth. It's been working. It's tough to put a finger on it, but as long as we keep winning games, that's the most important thing."
For Greiss, it was already customary after splitting last season with Robin Lehner and winning the William Jennings Trophy for fewest goals against. Varlamov, who signed a four-year deal with the Isles over the summer, has quickly seen the positives, as the split has the 31-year-old feeling fresh for every start.
"I feel good about it. When you play every other game, you feel fresh mentally and physically," Varlamov said. "When you play so many games in a row and then in some games you feel tired and exhausted and you have to get through that. When you rotate goalies, you can always feel fresh."
Varlamov has been especially good of late, winning his last four starts, stopping 125-of-131 shots (.954 SV%) over that span. That doesn't include Varlamov's 30-save relief effort on Nov. 30 against the Columbus Blue Jackets, when he entered the game cold in the first period after Greiss' dizzy spell. If there were ever a game that epitomized the two goalies working together, that's it.
