Seems like the coaches are getting line combinations sorted out. Colton centering for Privitera and Puffer worked well. Let them build some chemistry. Alvaro, Darrar, and Bowen have played together the last two games and are producing. That should be the top two lines that dress every game.
Lodermeier worked well centering for Misley and Esposito and that should be the third line until Blanleil is back. I think Lodermeier has been the most consistent center on the team.
For the fourth line I think you swap that entire line each game between Best/Kaufman/Petruzzelli and Cowans/Coughlin/O'Neil.
That is my uninformed opinion.
