By now you already know how scummy of a person Mike Babcock is. It came out, that during his time with the Maple Leafs he forced Mitch Marner to make a list of his teammates who worked hardest to least hard and share it with the team.
Apparently, teammates didn't get mad at Mitch Marner, a rookie who was just trying to please his coach, instead, one, in particular, turned against Mike Babcock. That player is now New York Islanders forward Matt Martin.
According to TML Updates, Matt Martin confronted Mike Babcock about the situation and wouldn't let it go.
