With 2 pt game, Plekanec ties Tremblay with 584 points for 15th on Hablist
Why would Byron be swapped? He dosent play any on the PP, is dangerous on the PK and already plays fewer minutes than Galchenyuk, while being more productive offensively with no PP time.
So you want to give Byron 3 or 4 minutes on the PP every game with no decrease in icetime, he likely would go for that. But then you know the dead horse beating posters would lose it if Galchenyuk then didn't play PP.
