I think we can agree that generational talent complicates the discussion; that's my gripe with Brady. Rogers was Rogers when Mike left, and Brady's best work has been with Burrow, Teddy (who Sean has already "fixed"), and Allen. That's a first-ballot HOF guy, a potential HOF, and a solid, proven starter.
There's always a bit of chicken and the egg with these situations. Is Brady propped up by having great talent or is he a good enough coach that he's chosen over others to work with great talent? The truth is probably somewhere in the middle.
