As in, not enough D?
Hajek, Raddysh, Rykov, are basically all they have. Crawley is another option, but I think the fact that they had him buried in Maine for most of the year tells you what they think about his game. Ebert is another option but he's apparently already looking to sign in Europe, so, no telling if he'd want to report. Day is gone. Not a whole lot of D to choose from.
I'd leave off one of Nieves, Andersson or even Gettinger and replace them with O'Regan, then bring Hajek, Raddysh, and Rykov.
EDIT: I do forget about Reunanen, but I think it's a tall task to ask a guy to step into the playoffs in the NHL after he has never really played in NA before. I know if it gets to him we're screwed, but still, I think you have to bring guys you'd have confidence in playing.
