Why can't it be? The Penguins have really good wing depth, to the point where they don't need McCann at wing. Why can't they just pencil him in as the 3C instead of continuing this journey to find the perfect 3C?
I feel like the problem is that McCann was bad at center for like 5 games last year and everyone decided he can't play center. It's why people are still saying that they'd rather have Lafferty or Blueger as the 3C over McCann, which was said a few days ago. McCann's just a good player in general, whether it's at center or on the wing.
