Although Maple Leafs captain Auston Matthews has provided his teammates with three assists, he has yet to find the back of the net in the series against the reigning champions.

Longtime NHL analyst Don Cherry shared his theory about what's going on with Matthews during Sunday's episode of "The Don Cherry’s Grapevine Podcast," suggesting the Leafs captain is not healthy. "I think he's hurt," Cherry said. "He must be, because he's not shooting the way he can."

Welcome to the deep waters, Toronto Maple Leafs. Having fun? It sure didn’t look like it for much of Game 4 against the Florida Panthers Sunday night. It was a physical, chippy affair, with both teams taking plenty of liberties before and after the whistles.
