That is true about Chicago, but their centers showed up in the playoffs. Patrick Sharp had a really great playoffs in 2013 tbf. Also, if Carolina's centers could show up in the playoffs then it would be a different story.
Sharp played out of position Cup #1. Cup #2 was an aging Handzus between two great wingers, Kane and Sharp. Cup #3 was an aging Richards next to Kane.
The team could really use some pure goal scoring ability, or just an infusion of high end offensive talent in general. And I think the folks in charge wouldn't have built things they way they did, if they were that concerned about position.
