Of course it isn't irrelevant, he's a sportsman like many others who by the age of 21 was a champion, like I already said we train up and send 16 year old to war, so to say a 21 year old who's been fighting in the UFC for 5 fights already wasn't ready is rubbish.
And cute? It's common sense sweety, what organisation do all MMA fighters aspire to fight in? Erm it's the UFC, why? Because they have the best fighters and pay the best, TV shows and being a WWE wrestler aside to get signed to the UFC you need a decent regional record, so if you've fought 5 times in the UFC logic would say you're pretty comfortable at the top level.
