No one has a clue if he can make it until any particular date. There's an old saying in sports, "He got old overnight", it happens. If he drops off and starts losing consistantly to journeyman, he may keep going, he has a ton of faith in himself, but no one can pick a date, he may say "don't have it anymore" tomorrow for all we know.
