They aren't RFAs because they weren't offered contracts by the teams that drafted them. They could make $4,000,000 if they were in the VHL, but yeah, $3,000,000 is the most they can make in the VHLM.
My issue is that Higgins first opted to try to just sign them all in the Helsinki contracts thread. I guess I also find there to be a bit of a flaw in that he can just offer them the max and no other team could contend with it. Not that I think any other team would've. Just kind of fed up with his antics going back to last season and in the thread discussing the Helsinki punishment.
