I'm not sure what development camp you watched, unless this post is aimed at 'mild trolling' of the Sens fans who are still anxious about giving him up.
From my observations Dahlen came pretty must as advertised.....skilled hands down low but hardly the fastest guy in camp.....in fact his skating will needs more work imo....and was he more impressive than Boeser, Pettersson or Juolevi?...hardly.
Dahlen could find his way to Utica, but more likely heads back to play another season in Sweden, hopefully in the SHL.....should be a lock for Sweden's WJC team though.
