I have to believe that Lou is going to be watching Bailey and Leddy very closely the rest of the way. As has been discussed, trading one or both for some mix of futures and/or cheaper assets is an easy way to free up money to try to add a goal scorer.
I am sure Lou will revisit the Parise trade first, because he would probably love to have Parise in the locker room and working with young forwards like Barzal, Beau, Wahlstrom, Bellows, Holmstrom, etc. If it is a deal that manages to shed Ladd, and isn't too cost prohibitive in terms of secondary pieces, I could live with taking on Parise's contract.
The rest of this season is going to be very important for a handful of Islanders players.
