The Toronto Maple Leafs, New Jersey Devils, and St. Louis Blues made significant roster changes over the summer, and their investments are paying off. Key players like Anthony Stolarz and Oliver Ekman-Larsson have excelled for the Leafs, enhancing their defensive and offensive play.

Meanwhile, the Devils' Paul Cotter and Stefan Noesen have provided high-value contributions on the third line, helping the team maintain a competitive edge. In St. Louis, Philip Broberg and Dylan Holloway are proving their worth after being acquired from Edmonton, solidifying the Blues' playoff aspirations.
