When the Nashville Predators traded for Ryan Johansen in January 2016, they did so with the confidence that he could become the top center that Stanley Cup-challenging teams build around. Their faith justified, the Predators agreed to terms with Johansen on a new contract Friday, he told The Tennessean. Terms were not disclosed. Johansen, who was a restricted free agent, tied for the team lead last season with 61 points, including a career-high 47 assists.
