The only Dmen missing is Wiz, save Methot tonight who's been average anyway. This blueline sucks with zero depth
Nikitin is out. Lebda is out. Martinek is out of the season. In Springfield, Holden is out for the season and Goloubef has been out for most of the season.
Howson made the mistake of hoping players would be ready (Savard & Holden), hoping players could stay healthy (Martinek) and hoping players could step up (Russell, Methot, Clitsome). But "hope" gets you jack squat in NHL.
Howson isn't blameless, but this clusterf'k of injuries was unforeseeable. A young defensive corps like this is going to have bad games. Unfortunately, the way defensemen in the NHL get better is playing, making mistakes and hopefully fixing them. And the fans have to suffer through it.
