Assuming no additions are made:
Next year Miller replaces either Moore or Boyle.
Lindberg replaces they other one, if they are not retained. If, for example, Moore is resigned, Lindberg stays in AHL and is first center up.
Fast moves into the RW spot vacated by Callahan. If Callahan stays or they get a linear replacement, Fast becomes first winger up and/or trade bait.
Kristo is next man up after Fast. He is your energy type call up. If the team needs some goals and to excite the fans you break the open in case of emergency glass on Kristo. Also possible trade bait.
Allen and McIlrath stay in AHL unless Girardi and/or Stralman are out. If, for example, Stralman goes Klein moves up to 2nd pair and Allen or McIlrath complete for 3rd pair RH spot.
