The following players are currently playing (and some producing) in the NHL, and are available to be signed as free agents to teams looking to add NHL depth.
Forwards:
Riley Sheahan - SEA
Johan Larsson - ARZ
Andrew Ladd - ARZ
Tanner Kero - DAL
Logan Shaw - OTT
Defenseman:
Marc Staal - DET
Josh Brown - OTT
Jacob Middleton - SJS
These players will wait and see if any offers come in before Wednesday October 27th, and then make decisions from there. Their preference will be to sign with teams that lack NHL players on their roster.
Also, keep in mind that there are many players currently playing in the NHL that are stashed on FL minor league affiliates. These players will be monitored throughout the year and if it is determined that they are full time NHL players, they will request NHL playing time. If this is not granted, they will request trades and/or walk to free agency.
