One of the most ridiculous things I have heard. When you hang a line on something like that you take into account the tendency of how many 3's you think the guy will shoot but there is no guarantee. If he goes some games without ever attempting one that should be factored into the line, not brought in as an addendment later. I wonder if he shot 12 three's (and made at least 2 of them) if you could have gotten a refund since he "shot too many" times?
Let us know the outcome please, this is the kind of stuff these forums are for. Thanks.
