1. Shake off the rust. The last time the Knights played, people were still filing their income tax returns. And the Sharks have been off since April 18. 2. Puck stops here. Knights goaltender Marc-Andre Fleury and counterpart Martin Jones of San Jose each posted a save percentage better than .970 in the opening round. 3. Kill joy. The Knights faced the league’s best penalty-killing unit (Los Angeles) in the opening round of the playoffs. They get the No. 2 short-handed team (San Jose) in the semifinals. 4. Fourth dimension. Both teams' fourth lines played pivotal roles in the opening round. 5. Fear the beard. Sharks defenseman Brent Burns, who played Game 4 against the Ducks after he missed the final 10 minutes of Game 3, practiced this week and is expected to be ready for the series opener.
