People buy jerseys of championship teams. That is the reason TD might have more jersey sales. If KG wins a championship or two, then his sales would be higher. You can not argue the fact that KG is more marketable, but TD could care less about that.
The point of the article is that winning is not as important as it used to be...these players used to make more money in the playoffs than in the regular season, now they take a pay cut, so it has lost its luster somewhat.
The most popular jerseys have been Lebron's, Carmelo's and AI's, and they have not won jack, but they are all wealthy beyond all comprehension.
