It has yes. The average fan has trouble looking behind the stats and results to determine how well or poorly a team or individual player actually performed. Your QB threw for 359 yds and a couple of TDs - great. But DVOA, which takes into account the opponent as well as the game situations, can tell you how that QB did compared to an average replacement-level player, based on the various down and distances and overall opponent adjustments. Your average fan may have a vague idea about that but DVOA can tell you within a much higher degree of reliability.
