"maturity" I don't think so
maturity would be jones showing up for the fight and keeping his mouth shut, he's no Zuffa businessman he's an employee. Maturity would be jones doing his job, no matter what he's asked, because he'll be making millions in the process anyway.
in his last year alone, he probably made enough to be set for life. his attitude is insulting for those who struggle with minimum wages and still have to feed kids and pay the bills.
he's immature, he's probably the most immature UFC fighter around these days. Bisping looks like a wise old man in comparison.
