Yeah, my concern with acquiring Kapanen for the top-6 is that he's more of what they already have. I think Kapanen is fairly similar to Zucker, which is a really nice piece to have but I don't know that you want your entire top-6 to be filled with Jason Zuckers.
But Kapanen's the kind of winger that both Crosby and Malkin like to play with, so who am I to question it? This top-6 wing group has basically exactly what Crosby and Malkin want: speed, youth, talent and scoring ability in a package that doesn't shy away from physicality. If nothing else, JR, Sullivan, Crosby and Malkin are on the same page for what kind of players should be surrounding them.
