For those first five times, who was the second best player on the Cavs roster? DeLonte West? Zydrunas Ilgauskas? Anderson Varejao? They had NOBODY. The implication in your argument that Lebron didn't make "his team/players around him better?" Come on.
I didn't love when he left Cleveland the first time (or the second time). But he absolutely makes his teams and teammates better--I don't think one can reasonably question that.
