I said fighters are pointless
Not physicality.
If we are talking about policemen is Dorsett really going to keep the Sedins "save"? Or does Kassian play with the Sedins keep them more "save"?
It's what Don Cherry said "When Bieksa is on the ice with the Sedins they grow 2 inches". When Bieksa was good (I still think he's decent) this was completely true. He's a physical force that polices the other teams top players by not being afraid to fight them. Dorsett, however, isn't good enough to play in the top 9. So his "policing" is basically limited to the 4th line.
This is why I value a player like Kassian so highly while not valuing Dorsett at all.
