I don't see why that should matter. What is the definition of a "palpable" error that the bettor can make and get his bet refunded after the fact? Of course none exists, it doesn't matter if your kid clicks a bet or you fat finger the wrong number or even if your own homebrew betting algo has a glitch, if you don't notice until after the bet has resolved you're just out of luck. As long as there is no "I made a mistake, get out of jail free" card for bettors there shouldn't be one for the companies serving those bets either. FanDuel would have collected this man's money if the Broncos had lost and they would have collected his money if he had clicked this bet accidentally, to that end he deserves to collect his money.
