The Sharks and Sabres are in similar positions, with San Jose winless through two games this season. Following a 4-1 loss to division rival Los Angeles on Saturday,coach Pete DeBoer cited the team's compete level at its main issue.
They've had three days to correct that, and Housley said it's important for the Sabres to be ready for a hungry team come puck drop.
"They're still a very good hockey team," Housley said. "They're going through a little bit of what we're going through. I'm sure they worked on a lot of things in practice these last three days, we've got to understand that."
The Sharks no longer have Patrick Marleau; the face of their franchise for 19 seasons moved on to Toronto via free agency during the offseason. Housley said having Marleau center the third line behind Joe Thornton and Logan Couture made for difficult matchups when facing the Sharks in the past.
But even without Marleau, the Sharks have no shortage of standout players, a group that includes Thornton, Couture, Joe Pavelski and especially reigning Norris Trophy winner Brent Burns. Burns led all defensemen with 79 points last season and led the entire NHL with 320 shots.
"He's a terrific passer," Housley said. "I know he can use his mobility and he's a big presence out there, but he's a terrific passer. He always finds the open man, and I think that makes him unique. It just seems that his shots always get through, he changes his angle terrifically, and he does it quick. We're going to have to pay attention to that, especially with our D-zone coverage.
The Sharks will be without defenseman Paul Martin, who is day-to-day. Joakim Ryan, a seventh-round pick in 2012, will make his NHL debut in his place.
