your smoking crack will never turn pro
he finished high school and sat around for 2 years, then trained for a year and won a show, then gained a lot of weight. He has some flaws, sure, and it might be 2-4 years til he's fixed them.
But he could be a top pro. Back is bad, conditioning is bad, some say he's a mess. But he has a boatload of potential, he just needs time and good advice.
Bottom line - he has more resources behind him than ANY other amateur. He has pro legs, and if he can get the top to match, he can move up.
