He'll be wealthy soon
He will NOT be wealthy soon. His antics cost him that. Third round money will probably be $500,000 per year. If he does extraordinary things he can parlay that into wealth later on, but assume he stays at that level for a typical five year career. He would earn about $2.5 million; pay half of that in agents fees and taxes; barely be able to support an NFL lifestyle with the rest; and retire with nothing. He'd be in his 20's with no money, no skills, and most likely suffering from depression. He'd spend the next decade being paid by some upper end nightclub to hang out there drinking with the patrons. He'd do that until his value faded or until he was so besotted that he couldn't show up anymore. Then, at maybe 40, is when he'd move under the bridge. This is his future if he can't whip his addictions.
I sure hope, instead, that he gets on a team, plays at the level we know he can, and gets to sign the big contract later. But there's a lot of ifs between now and then.
