Unless it clearly stated "Player Must be Drafted.." OP is in the right and should be paid... and Unders should be graded as a loss.
Even if Player Must be drafted, its a bullshit wager...
You're not betting 45.5-60 picks, You're betting OVER 45.5 Picks, Once that 45th passes, you WON.. you shouldn't then be on the edge of your seat hoping that he is drafted so your wager wins.
Sports betting is handicapping right.. He handicapped it correctly, that player wouldn't be drafted in the 1st 45 picks...
Absolute BS to claim anything else...
