Lifted this from Reddit, quoting a post-game review by The Athletic:
"There’s something wrong with Paul Byron.
And it’s not just that he’s no longer coming close to scoring, though that’s certainly a worrying trend. In 13 games this season Byron has managed just nine shots at 5-on-5, half his shot rate from last season.
Perhaps it’s because we’re used to him outskating anyone not named McDavid or Grabner, but Byron looks slow out there.
He’s also giving up the puck with a lot more regularity and is continuously losing his defensive zone coverage.
A cursory glance at the statistics would say otherwise, but Artturi Lehkonen isn’t quite in the same boat. He’s actually creating chances, and if it weren’t for the fateful Friday the 13th when he saw a black cat as he walked under a ladder, he’d have a lot more goals."
If this is going on, why don't the Habs sit Byron? What's the point of keeping him out there, he's not himself. Something is going on, everyone is noticing it. Byron is a liability at this point.
