I think Zetterlund and Bahl should be full time Devils next season.
Zetterlund should replace Vesey minutes as a plug and play bottom 6er.
Bahl should replace Colton White as the teams new 7th dman.
I would trade Zacha and give his wing spot to Holtz. He doesn't need another year in AHL.
And release Geertsen to open a forward roster spot for a free agent signing.
Either a 3C if we want to keep Mercer at wing or a top 6 winger if we want to return Mercer down to 3C.
Bahl I believe can play another season in the AHL without having to clear waivers, so let him develop there.
Zetterlund would have to clear waivers, but his season this year demands he gets an NHL oppurtunity next year. All signs point to him earning a spot.
The Devils are going to pencil Holtz in as well. He's going to start the season in the NHL, and if he doesn't stick that would be dissapointing.
Boq is very likely our 3c to start next year.
Mercer is top6 wing, and depth center.
Between Zacha Johnsson Tatar I think you trade whoever you can get the most for. Maybe two of them.
