The Pens 4th line will probably get filled in by better opponents but given the strength of the top 9, they might not play much. They'll just need to add some better grinding depth players at the TDL if they want a deep playoff run, but it should be possible to do

O'Connor will make the team. I think Pitlick is going to have a hard time making the team since he's the most expensive of the fringe players.

Honestly the 3rd line is what worries me in this lineup lol. That 4th line actually looks pretty decent for a 4th line.
