The Toronto Maple Leafs first day of work with their special teams in training camp revealed some significant personnel changes.
Auston Matthews got his first action as part of the Toronto Maple Leafs penalty-killing unit. Head coach Sheldon Keefe previously discussed his plan of using his star centre while shorthanded.
The other notable change saw John Klingberg replace Morgan Rielly as the quarterback of the first power play unit.
The preseason is the appropriate time for experiments, but each of these moves carries some risk should they continue when the regular season starts.
