The stats kept by the ACC and NCAA don't make any attempt to differentiate the level of competition. A game against Murray State counts the same as Alabama.

You can see the flaw in that book-keeping. With all due respect to Richmond, William and Mary, the CAA at-large and the powers of the Southern Conference, a statistical database that only included Division I-A teams against Division I-A teams would give a more accurate portrayal of a team's strengths and weaknesses. (Yes, I know Army and Alabama aren't equal either but at least we're comparing widgets to
widgets.)
