I think it's pretty obvious that these guys are the youngest. But which is the youngest of them all? Sage, whose regional show skills + grindr abs got his ass swiftly kicked in a fox co-main? Holloway, who fought a prime Mcgregor at only 13? Or Jon Jones, who is so young he can afford to spend half his 20's suspended, drunk in the club or stoned watching cartoons, yet still shreds LHWs like they are playdough? You be the judge.
