The thing is though, Dubnyk just wasn’t traded away and became awesome overnight.
He was traded to Nashville where Mitch Korn saw so many flaws in his fundamentals, he said I can’t fix him. Nashville flipped him to Montreal and he rode the bus for the Bulldogs the rest of the season.
Nobody offered him a contract until Arizona gave him league minimum. He took it upon himself to better his game or be out of the league. He took some head trajectory course, worked on his fundamentals (basically reinventing his game) then became a good goalie in AZ and for Minnesota, where he played a long time and was a legitimate starter.
