The formula for an effective power play has never changed as long as Daniel Alfredsson has been in the NHL.

That’s 18 seasons, during which he’s been a big part of many successful Ottawa Senators teams, and been one of the better offensive players in the game.

So Alfredsson knows how to put the puck in the net.

“For any successful power play, as long as I’ve been in the league, you always come back to the same thing,” said Alfredsson after Tuesday’s 5-0 loss to Philadelphia in which the Red Wings went 0-for-4 with the man advantage. “Shoot the puck and get people in front.

“We’ve got to find a way to get some more pucks to the net and give this team some momentum.”

Without Pavel Datsyuk (lower body), Johan Franzen (concussion) and Henrik Zetterberg (back), the Red Wings aren’t likely to score many goals these days, especially at even strength.

So that makes the opportunites on the power play that much more crucial.

But in the absence of Datsyuk, Zetterberg and Franzen, there are some players who’ve never been on an NHL power play…

“Ever,” coach Mike Babcock said, finishing a reporter’s question. “We hit three (cross)bars. We had some opportunities, but we didn’t score (Tuesday). Any way you look at it, we’ve got to be better.

“We have to really focus in on that in our practice and get ourselves dialed in.”

The sooner, the better. The Red Wings, for the month of January, are 4-for-50 (8 percent).
