"All this season, the Red Wings have been one of the best defensive teams in the league.

With a 2.36 goals-against average (6th in the league), they've been able to succeed in improving last season's difficulties in that area.

But in the last four games, the concerns have resurfaced.

The Wings have allowed 15 goals during that span (two of the four games were losses). Tuesday's 5-1 loss to the Islanders was particularly scary, with numerous breakdowns and odd-man rushes."We weren't very good," coach Mike Babcock said."
