But that wasn't the contract, the contract was "$9 million during the length of the contract plus $9 million deferred". The value of that $9 million deferred is not $9 million today.
I don't know why you're arguing against this when people are clearly explaining why you're wrong. This isn't a 3 year, $18 million deal. The AAV is calculated based on the amount of money you need today to be able to pay Vatrano $900k a year for 10 years from 2035-2045. With how the NHL calculates it, you need $4.71 million in money today to be able to pay Vatrano $900k a year from 2035-2045. Because of that, the NHL divides that $4.71 million by the length of the deal and adds that money to the AAV.
