I have been offered Edler for Spezza. I am trying to upgrade my D but I'm not sure if this makes sense. We set lineups weekly and play 6 f and 4 d. My forwards are Malkin Marleau Spezza Alfreddson Jagr Toews Semin Eberle Jokinen. My D are Whiite Gonchar Subban Burns and M. Green. I am slightly behind in games played in both d and f. With Green hurt, unless I get another D I will not catch up in games played. Spezza has been pretty hot. Does this trade make sense?
