Out of this list, only Florentino (Buffalo), Cowley (Florida) and Josephs (Pittsburgh) have been invited to development camp. (Correct me if I'm missing anyone)
Since these three players are already signed to AHL contracts for the upcoming season, it's highly doubtful that they'll be offered ELCs before the August 15 deadline.
If they opt for free agency, Will Butcher (Colorado), James De Haas (Detroit), Alex Kerfoot (NJ), Blaine Byron (Pittsburgh) and Dominic Toninato (Toronto) will certainly attract NHL interest.
---------------------------------
In other news, the Leafs seem to have cut ties with 2016 draftee Jack Walker.
The former 6th round pick is currently attending Minnesota's development camp.
