Billionaire Warren Buffett is offering up a sweet March Madness deal -- $1 million per year for life if you can correctly predict the Sweet 16 field.

Buffett is also offering $100,000 to an employee who has the most correct picks, according to CBS Sports. Eight employees tied for that last year and split the $100,000.
