Both the Detroit Red Wings and host Pittsburgh Penguins are struggling as they prepare to square off Wednesday.The Red Wings have lost their past two games while being outscored 7-1, and the Penguins have lost three of their last four.Detroit fell 4-0 to the New York Rangers at home on Saturday after losing 3-1 to the Toronto Maple Leafs on the road in the Hall of Fame Game on Friday.There was one positive in the loss to the Rangers. The Red Wings actually had a pronounced shot advantage after being decisively outshot in most of their games this season. They had a 37-24 edge, but still could not dent New York goaltender Jonathan Quick.”Stay with it,” Detroit coach Derek Lalonde said of his message to the team. “I know it sounds like a cliche but trust the process. I don’t like the fact you play a game like that, and we don’t have another crack at it (another game) until Wednesday. Guys will have to sit on this one for a little.”I don’t know if I’ve had a more frustrating hockey game while coaching for 30-plus years.”The Red Wings dominated in time in the offensive zone, hit goal posts and missed open nets.”We definitely produced some looks and odd-man rushes,” forward Patrick Kane said. “Throughout the season you’re going to have games like that. What we can take away is we created a lot and obviously we have to find a way to get pucks by the goalie.”Wednesday night’s contest is the beginning of a four-game road trip that then takes Detroit to the West Coast with games in Anaheim, Los Angeles and San Jose.The Penguins were hammered 7-1 at home by the Dallas Stars on Monday night; they found themselves down 6-0 in the first period when they allowed six goals in a span of a little more than 16 minutes.
