EDGE Analysis

After a disappointing 2021-22 season, Johnson got off to a fast start in his second year with Chicago, scoring a pair of goals with four assists in his first six contests. The Blackhawks have yet to announce a corresponding move, as they'll have to shuffle their top six in Johnson's absence.
