The Toronto Maple Leafs were one of the pleasant surprises of the 2016-17 season. The biggest reason they were able to make the playoffs last year was because of the play of their three terrific rookies: Auston Matthews, William Nylander and Mitch Marner.

Matthews and Nylander are off to roaring starts (Matthews has eight points in five games, Nylander has five points in five games). But things haven’t gone as well for Marner, who has a four points in five games.

That’s far from a poor point total for the sophomore forward, but head coach Mike Babcock hasn’t been impressed with his overall play (for whatever it’s worth, he’s a minus-6 this season).

On Monday, Babcock tweaked his lines, which shocked the fans and media in Toronto. Marner was no longer skating on a line with Tyler Bozak and James van Riemsdyk. Instead, he was with Dominic Moore and Matt Martin on the fourth line.
