No you certainly do not.
If I decided I wanted to fly an aircraft tomorrow, but didn't take the requisite time to earn a pilots license, no one would call me courageous.
It is the height of delusion and sheer egomania that someone with no combat training thought they could just 'become' a professional fighter by showing up.
Mike Jackson isn't high enough caliber to make it on the regional MMA circuit, let alone the UFC, it is truly an embarrassment that he was signed. The fact that Phil Brooks is so poorly trained he looked helpless against a journalist with virtually no experience highlights the delusion.
Brooks had as much business cage fighting last night as he does doing any dangerous job he's completely unskilled at. It's flat out stupidity and ego driven fantasy.
