They can offer 1 billion dollars for a prize and no one on this planet can have a perfect bracket. Two #2, one #4 and one #5 out in first round and the night is still young.
so what your saying is I could start a local bracket contest where a perfect bracket wins 1M$
charge a $20 entry fee and walk off with the $60 from the only3 suckers that were naive enough to buy in...
on another note has anyone ever won any of the yahoo's perfect bracket payout?
Nope. Nobody has ever filled out a perfect bracket (or at least proven it).
That's the number of combinations. The odds of actually filling out a perfect bracket would be considerably better since many favorites typically win outright (such as one seeds versus 16 seeds). However, it's still highly implausible.
