Adding a new player that makes 2 million plus would be a net negative.
We could just replace Eriksson with someone already on the roster, like Leivo (who already makes 1.5)
So it becomes 2019-2020: Eriksson 6 million Leivo 1.5 million = 7.5 million
In the 2021-2022 season: Eriksson 4 million (buyout) Leivo 3 million (assume his salary DOUBLES, which it might not) = 7 million. Still a savings.
Or either Hoglander, Lind, Podkolzin, etc may be a low cost borderline 2nd line option by then.
