How are Willie's calls graded?
The short answer
Before kickoff, every call gets a time-stamped receipt that can't be edited. After the final score, it's graded against the number on that receipt, and the result goes on the public record.
Because the receipt is locked before the game, nobody, Willie included, can quietly change a call after the fact or drop a bad week.
The record page shows every graded call with the date and the line it was graded against.
