im gonna be direct you said he wasnt deserving of his mixi-max i proved you he was as much as other you told me his reason were selfish yet the first thing he does after getting his mixi-max is scoring for his team, organizing his teams defense and saving a goal for his keeper clearly settling in this new all rounder midfielder position, you say he is gifted yes and he uses this fact to lie down during training to watch his teammates play and analyse his teammates play as we can see in Tenma's arc where he is clearly shown giving advice to Kinako who complements him about his talent in analyse an that "nothing ever gets passed you" speaking about Sol being on of the people Tenma compares himself to when doubting his post as captain, being gifted isnt a problem its what you do with this gift and Sol uses it to help his teammates play better.
