If he wasn’t coming off multiple mystery wrist and back injuries, I’d say Matthews and the Leafs are idiots for trying to be Bergeron/Barkov when he has preternatural scoring ability. But since he is just scoring a pedestrian 40ish without doing anything on the PP, sure, why not strive to be a shutdown centre while doing it.
This is why I brought up the Yzerman comparison. You know the lore that surrounds the transformation of Yzerman from perennial 40 - 65 goal scorer, to a dude who gave all that up to become a Stanley cup champion after a single conversation with Scotty Bowman..
