Christian Dvorak
Dvorak was a project that the Canadiens tried to acquire from the Arizona Coyotes. He had problems staying healthy sometimes and didn't fit in the desert. The consensus was that Dvorak could come to Montreal and excel in an elevated role for a team desperate for help down the middle.
He had a good start to his Canadiens career, with 33 points in 56 games. He regressed to 28 points in 64 games the following season, then recorded just nine points in 30 games last season.
The good news is that the Canadiens can get away from their gamble after this year, as he has just one year left at $4.45 million. The bad news is that we must watch another year of Martin St. Louis struggling to find a role for him.
