A little late for the party, but here's my $0.02 on the Ruutu trade.
While it wasn't really a "great" move that wipes away the scoring woes, I think acquiring a player with good reputation was a proper move to make, especially when putting it into a context. The deadline is a pretty delicate situation to bring in new players or substract them especially now when the margin for error has grown thin.
I think it was for the best that Lou chose not to rock the boat and stir the dynamics of the dressing room. As of now, the new acquisitions need to be shoe-ins, since there's not really an adjustment period available for fine tuning the lineup and searching chemistry.
I guess only time will tell, how it translates on the ice, but at least on paper Ruutu fits the bill as a player who is able to contribute from the get go on whichever position he's put into. Hopefully this turns into a trade and like the first Ponikarovsky trade, and the Devils wind up getting a useful individual in Ruutu and settling the depth chart, namely pushing Gionta and Bernier out of top 9.
