Lebron definitely was a pioneer. His situation was more understandable then Kevin's. Lebron was surrounded with very average players at best. Zydrunas Ilgauskas, Anderson Varejoa, and Mo Williams are not reliable options. He wanted to win but wasn't provided the tools needed to win. Kevin on the other hand, had a monstrously defensive front court of Steven Adams/Kendrick Perkins and Serge Ibaka, and the two main MVP candidates of this season at his side at one time and still couldn't win a championship. Kevin's decision was very poor for his popularity and appeal to every other fan. Lebron's decision was very controversial back then, but he is now known as a hero. He is the super hero that needs to kill the villain.
