I don't think it is a joke for two reasons:
1. Dan Bylsma is without a doubt the bestest, most proactive coach in hockey. Fastest to 200. Jack Adams. 25% think he's the smartest. Won Capitals cups the last few years. Won a Stanley Cup in '09. He can IMMEDIATELY sense if something isn't working and will make changes. So, why would you be surprised that he, once again, sees need for change and opportunity where know nothing fans like us are too busy chanting 'let's go Pens', 'get to our game', and 'best line in hockey' to notice.
2. At morning skate, Dupuis was screaming '**** you Geno' any time he was in shooting position.
Seriously, some of us remember the disaster of Dupuis with Geno in 2009-2010. Fact is, Dupuis' speed is going to help a lot. And, I do remember late last season, when Neal was out for a game, that the one game where Iginla looked good with Malkin was when Iginla was at RW and Dupuis filled in at LW.
