With the offseason in form, there are usually two times during the summer when fans are highly interested in the NHL. One is the NHL Entry Draft as teams that have not done well in the regular season or over many seasons attempt to build their team out with draft picks better quite strong.
With those players available, I expect all three to be picked up by some team next year. Though I don't think they will pick up high-level contracts as most of them are on the trailing edge of their careers.
