He wouldn't be what he is now, and would likely end up in a much worse position ufc career wise. Thing is, and what I noticed looking him up since his first appearance in the ufc, the age made him more intelligent and capable of evolving at the pace he is now. Yes, he is a great athlete, but that we already have tremendous athletes in the ufc who can't perform, being a good athlete doesn't grant success. What gives him his achievement is his specific attitude and approach which you don't see in young fighters. That I noticed and since rooted for him throughout his ufc fights even though all considered him an underdog with quirky style of fighting. What people didn't seem to see in him was his calmness, his interviews where he talks about how he trains, the way he adjusts in the fight, the way he adjusts and evolves after each fight, and his daring "quirky" moves which he does in confidence knowing his athletic capabilities. He is so great now because he is old(experienced).
