Because the first three lines are set, both Lycksell (23) and Bellows (24) are better served playing big minutes in LHV than on the 4th line in Philly. Bellows actually had good metrics in Philly, just couldn't score to save his life (pressing?).
Who do you sit on the first three lines? JVR is being showcased, Hayes needs to build his value for a summer deal, same with Laughton, you gonna sit Allison? The 4th line generally plays 8 minutes a night, do you want to stick Lycksell with Brown and MacEwen?
At the TDL, JVR is a good bet to be moved, maybe Laughton, a couple others.
Hayes will probably wait for summer, same with Provorov due to cap implications.
There's no rush, if the Phantoms make the playoffs you might keep them there to play major roles in an AHL playoff than play out the string in Philly.
