After a season that saw the Dallas Stars go from Stanley Cup hopefuls to a team sitting at home watching Alex Ovechkin and the Washington Capitals win it all, it's time for the organization to retool and attempt another championship run in 2018-19.The Stars hired new head coach Jim Montgomery to replace now retired Ken Hitchcock on the bench, and key pieces Jamie Benn, Tyler Seguin, and Ben Bishop are just a few of the names that will be back in Victory Green next season.But there's always some roster shuffling in the NHL.
