NSH probably accepts -- but I don't know if they'd want to retain on that contract considering it's already pretty low. If they sell off their players, they'll probably retain on Granlund, Jarnkrok (or similar forward with another year left), and Ekholm (big if) to maximize those returns, which would have them at 3 retained contracts. Now if they don't get into that retention trouble, then yeah -- NSH accepts.

Detroit passes, You're not even close for Anthony Mantha. We'll give you Helm+Glendening+Cholowski for William nylander.

lol, Mantha wouldn't even get you Nylander. Nylander > Mantha
Also, I feel like two good top 9 forwards, an A level Prospect, a B level Prospect, a C level Prospect and a first would be close. I It might not get it done, but its definitely close.

If Toronto wants Mantha they are going to have to give up Sandin or Lehtonen.

No retained salary on Mantha.

To TOR: Mantha + 2021 3rd.
To DET: 2021 1st + Sandin + Kerfoot + Mikheyev
