McLellan added that neither Antti Niemi nor Alex Stalock know the answer.
"I'm ready to name him," McLellan said Monday. "I'm just not going to name him."
Niemi -- the Sharks' No. 1 goalie since he arrived in San Jose before the 2010-2011 season -- struggled down the stretch with three losses in five starts before Saturday, when he rebounded to make 30 saves to help lead the Sharks to a 3-2 win at Phoenix. McLellan said after the game that he was pleased with Niemi's performance.
Stalock has had an impressive season in spot duty, going 12-5-2 with a 1.87 goals against average. On Friday, he made 32 saves in the Sharks 5-1 win over the Colorado Avalanche 5-1.
Niemi has started all 33 playoff games for the Sharks, going 16-17.
"It going to be a great challenge," Niemi said last week about playing the Kings. "We had a tough series last year. I think they are a good team, a talented team that plays hard, which makes it fun to play against them."
