It also continued a hyperactive July for general manager Stan Bowman, who has also traded Duncan Keith and acquired Seth Jones in the past two weeks. Johnson, a 30-year-old center, has seen his production decline in recent seasons, down from a career-high 72 points in 2014-15 and an impressive 47 points as recently as 2018-19 to 22 points (in 55 games) last season. But the Hawks will be able to offer him more playing time than the stacked Lightning could, and he does boast 116 games of playoff experience and two Stanley Cup rings. He was Tampa’s leading scorer in their 2015 playoff run that the Hawks ended in the Cup Final.
