Which two players would come out of the lineup for that to happen? Harkins is playing well, I think he knows what he has to do to stay in the lineup. Defensively he's still a questionable player I think. At best when Ehlers comes back I think Harkins stays up with the team, over Toninato. Might keep that job for awhile, as I think Barron won't be back with the Jets until January, being eligible to get back up to speed with the Moose.
Probably get Sak-Lowry-Appleton as a checking line, and AJF-Gus-Gagner as a 4th line.
Appleton's had 2 good offensive games, but I think otherwise he's been very quiet on Scheifele's line, maybe negating offense, Ehlers will make that a top line in the league.
It is ingriguing though, to think what Ehlers could do for Gustafsson's offensive game, if the Jets wanted to go that way.
I still think the 2nd line is set because of the board work Dubois and Wheeler do, Perfetti isn't a strong board player, and these two help him out a lot.
