I wouldn't be surprised at all if Leon is nursing a shoulder injury. A good indicator for arm/shoulder injuries is how much a player is willing to shoot. Leon hasn't been shooting the puck with near as much frequency or as well as he is capable of. There are a couple of examples I could point to even from last game where the Leon of old would have taken a hard shot from further out, instead he tries to make a play to the inside, either with a pass or trying to drive it through himself. I don't have any stats to back that up and like you said, there's notihing official, just rumours. But that alone leads me to believe that he's nursing something. Also, his trademark "sweep shot" one timer from the low circle hasn't been near as effective this season as in past. I'm guessing due to a combination of a possible injury and goalies likely know about the low play to Draisaitl for the one-timer and are more prepared to stop it as a result. I still think he's distributing the puck well though. Threw a couple hits last night which is a good sign too. Overall not his best performance, but I'm not worried about him come playoff time. He seems to have trouble getting engaged for Regular Season games.
