I dont get this take. If the line stays healthy, I think the line gets 85+ points out of chytil and kakko.
The "kid line" in gallant's last year, was 120 points. Laf had 39, kakko had 40, and chytil had 45.
Now replacing Cuylle for Laf is a downgrade, but Kakko and Chytil are very good together.
Additionally, Lavi is giving this line lots of ice time, that Gallant never did.
Gallant kept them at 10ish minutes of even strength time at most.
They were 13+ in game 1. The better they play, and they tend to play the most how Lavi wants. The more ice time they're going to get.
