Okay, maybe you think the term “devastating injury” is an overreaction. Not me. There is a reason this “Career AHL’er” with 54 fairly nondescript NHL appearances is playing game in and game out. Is it because Mirco Mueller is setting the world on fire? Not really. His plus/minus is 0 and Mueller has no goals and only two assists to his credit. Is it because the Swiss product is growing into his game defensively? Sure, that’s part of it. Mueller is making better decisions with the puck, using his body and blocking more shots in the past few weeks.
