With the injury to Stephen Weiss there is no logical center to play alongside Daniel Alfredsson on Detroit's second line. There is also no left winger as Johan Franzen in on the shelf as well. Darren Helm centered Aldfresson and Tomas Tatar at practice Friday. However Helm, who is still not at full speed after missing 18 months of hockey, is not ready for second line minutes. Detroit coach Mike Babcock will not split up natural centers Henrik Zetterberg and Pavel Datsyuk in order to solve the problem. "Someone else is going to learn how to play in the second hole and play well," Babcock said. No telling who that will be, though.
