Most everyone is happy the replacement referees in football are gone. But this guy may wish to send the replacement refs a bouquet of roses, or something. He won $725,274 on $5 bet on a 15 game parlay bet (that means you have to pick 15 games correctly against the spread, without missing a single one). It is nearly impossible to win a 15 game parlay, as the payout ratio reflects.
Still, if football gambling were easy to do online here in California I'd probably put $1 on a 15 game parlay every week, like buying a scratch-off lottery ticket.
