I do believe that Hall and Hoffman are (or were) potential Lou targets this offseason, but those acquisitions get harder to imagine when the cap stays flat... after RFA's are resigned even to modest deals there isn't much available. somewhere between 5-6 million and that includes Ladd buyout and Leddy move for picks.
If the Isles cannot add someone like Parise (buyout), Hoffman, or Hall via free agency, then the options are:
A. Leddy trade for comparable top 6 F (IMO an example of comparable top 6 are Palmieri, Saad, or Tatar)
B. Mayfield trade for comparable young F (IMO example Kapanen)
C. From within (example Bellows, Koivula, or Wahlstrom)
D. Lower tier Free agents (example M. Granlund, C. Smith, Toffoli, Galchenyuk, even a Josh Leivo)
E. Look at F w/ bad contracts (example Hickey for Baertschi move or Leddy, Dal Colle, Hickey, + for Skinner (with salary retained))
