This is normal with many sites and I suspect site hierarchy heavily influences what you're seeing. Your site can only prop up so many of its pages, the rest require incoming links. I'd suggest getting more of those instead of redesigning your sites internal link structure.

Changing internal link structures by moving articles around will surely have unintended consequences elsewhere.
