FMPOV, popularity being defined as the favor of a particular group of people, in this case the judges. The winner is the most popular amongst the judges (whoever they might be) - like the Heisman, Academy Awards, Coach of the Year, MVP etc - Typically when there are judges involved, they are subjectively selecting a winner. As opposed to being an objective measure, such as the fastest person in the 100 M at a track meet, which would not be a popularity award.
I don't know how Elite 11 is named, it may be objective or subjective.
