The Maple Leafs are fragile at centre, and their second- or third-best player needs to see the ice more often.

The Toronto Maple Leafs seemed to want to play only one line in Boston, and with good reason.

Auston Matthews, Mitch Marner and Matthew Knies logged over 11 minutes together over the weekend and played well, winning almost 70 percent of the expected goals while contributing a goal. (Marner and Matthews also factored into the two other Leafs goals, as well as the deciding goal against, in a 4-3 overtime loss.)

The problem: Head coach Craig Berube had nowhere else to turn.
