(AP) -- The San Jose Sharks tout one of the NHL's most dynamic offenses. Their lack of defense, however, is a big reason the team is riding a three-game losing streak.
The Sharks look to tighten up their defense Saturday against the visiting Buffalo Sabres, the NHL's lowest-scoring team.
After opening the season with consecutive shutouts, San Jose (4-3-1) has allowed 25 goals over its last six games. The Sharks are coming off Thursday's 5-4 defeat to Columbus after falling to Boston 5-3 two nights earlier.
