Quoting: Melnyk_0ut
Lassi was just a throw-in piece since Ottawa doesn't have a spot for him whereas Berggren would be the centre piece of the deal coming the other way. He seems to be the odd guy out with all the additions Detroit made anyway
Detroit doesn't have a spot for him either. Berggren is not the odd man out. Detroit signed depth players. Fischer, Sprong, Kostin were brought in for depth.
Raymond, Larkin, Perron - 1st line
Compher, Copp, Berggren - 2nd line
Fischer, Rasmussen, Kubalik - 3rd line
Kostin, Veleno, Sprong - 4th line
Depth forwards who need to win a spot and beat a vet guy out. Zadina, Kasper, Fabbri (probably just not healthy)
Berggren is cemented in the top 9. He earned his spot last season.
