Leafs dont disclose injuries but anyone doing some research can put 2 and 2 together. In 2015, Matthews missed 14 games in the swiss league, just after his 18th birthday with a back injury. Back injuries linger, does anyone here recall the hit he took from an Islanders player in his 2nd year i think? The sudden disappearance in the playoffs, etc. Matthews from my stance, has lingering back issues, when u have that your whole body shuts down, skating and taking his level of wrist shots would cause major pain. I thought he looked out of shape this year but that doesnt appear to be the case.
