Pieces to the Rangers' Puzzle

It seems to me that the team to beat right now is the New York Rangers. Granted they lost last night to the Capitals, but every dog has its day. The Rangers lineup is extremely powerful and crafty, and that shows in their 22-9-4 record. The question I pose to ask though is just how long will it last? Clearly the New York Rangers are not perfect. In my opinion, and the opinion of other fans as well, they could use some help in terms of a scoring left winger. 

     At the center position, the Rangers have a one-two punch of Brad Richards and Derek Stepan. At the right wing, they have a pick your poison in Ryan Callahan and Marian Gaborik. Before the February 12 trade deadline the Rangers need to add to their arsenal. It is understandable that NY has come this far with what they have, but you're goal is to attain a Stanley Cup, and I just don't see it happening with this roster.
