I think He would be a champ even without Jackson. Everybody says He`s talented etc. but It`s not about It at all. His mindset is what got him where He is, his unshaken belief in himself. He sets the bar for himself really high, He doesnt want to "just win", He want to beat them at their own game, which They perfected over the years.
In one of the UFC embedded videos He says that in his first year of wrestling He had a record of 10-30 or something like that, but He overcame any obstacles and managed to get good at It. If You look at his brothers It makes You think that his strength comes from his upbringing. Its probably his parents who planted that much self confidence and self belief in him and his brothers.
I`m looking foward to see him outcain Cain
