IMO would rather waive Janmark than Ryan, we know Ryan is a good bottom 6 fit in many ways, not sure about Janmark. One of the two needs to be waived to have a 21 man roster. Benson has been a strong checker and pest - no clue on offense, but ultimately, he's cheap and brings a good element in 8-9 minutes. That third line will play a lot, and McLeod and Ryan should get lots of PK. Could also play 7D with Nemo and sit Benson depending on matchups.
I forget if Broberg has bonus considerations - if so keep him up on opening roster, but make the switch for Nemo quickly - Broberg needs to play huge minutes in Bake to settle into the season IMO, whereas Nemo is a useful low minute situational player to get physical - needed.
