Wings quote: "We feel pretty good about ourselves. I just hope we can keep our momentum going and our success going. We know we're playing another great team." - Detroit's Chris Chelios after the Wings eliminated the Sharks.
Ducks quote: "We weren't very sharp. It just seems we never really got into the groove of the games from a positive standpoint after that. Our focus has to be at the top of its game for the first period of the first hockey game. It was monumental last year that they were able to come into here and really stole the first two games. We didn't score. Our frustration level got up at times." - Ducks coach Randy Carlyle on his team's Game 1 loss to the Oilers in last year's Western Conference final.
