That vote includes fans too and is often a joke (Brett Favre is an example). If they led the peer vote specifically, that makes for a better argument but I believe that players can either only vote for players they've played against or cannot vote for those they've played - don't remember which. Either way, most players that vote have not seen both players, as the Titans and Vikings had almost no games in common. And even among the ones they did, the receivers are the only ones that would really know how well the corners were playing. The All-Pros are usually the most accurate judge. Those were Asomugha and Finnegan, even in Winfield's best season.
