I said on the first page, this likely foreshadows a Kerfoot trade. They're basically the same archetype of player. They'll use the extra cap space to add 1 or 2 of the remaining middle-six forwards on the UFA market.
I assume (and James Mirtle has been saying this for a while) that Holl is also gone. That opens up $5.5M in cap space. Benn will be on the roster as the 7D. I'll even leave Simmonds as the 13th forward for "leadership". Then start all of Clifford/Anderson/Gaudette/Robertson on the Marlies and the Leafs have $7.7M in cap space for Sandin, Engvall, and any other additions they can fit.
I'll pencil $2.4M x 2 or 3 years for Engvall (he has a pretty decent case in arbitration) and the Liljegren contract for Sandin. That then leaves them with almost $4M in cap space.
I think the Leafs could add 2 or 3 of ZAR, Milano, Heinen, Rodrigues, or Motte with that amount of space, depending on how long they hang around the market without a job. That would do a lot to bolster the bottom-9. And you could still waive Simmonds for another 900k in wiggle room.
