To your point, Dave Lowry definitely seems open to putting Perfetti in the top six. Which historically was a no-go for young players on this team. So putting him with two talented players, as you say, could bolster development. Lowry seems to have a very fluid thought process on how the line up evolves intra-game (is that grammatically correct?). I find that refreshing.
Ehlers and Connor both honed their skills playing alongside the Scheifele-Wheeler duo. Laine had to suffer the ignomity of such a poor centre as Bryan Little, to his chagrin.
Lowry does make more adjustments to in game rosters than Maurice that's noticeable. He gets down to 2 lines late in a game with a lead. And so far only Connor off that line is in that formation.
I think Perfetti is being put in a spot the Jets and Lowry see him in next year. As for this season, it's hard to say. I think there is some internal competition going on.
It looks like the lineup Lowry has in mind is
Ehlers-Scheifele
Connor-Dubois
Copp-Lowry
And where the other wingers end up is up in the air at the moment.
I do find it somewhat interesting that there is alot less chatter about Svetchnikov being on the Dubois-Connor line all of a sudden.
