The deferred money is his 2019-2021 contract salary. He's owed $35M in each of 2019, 2020, and 2021, but those salaries are deferred, without interest, to $15M in each of 2022 thru 2028. It actually makes the contract cheaper in real dollars (tomorrow's money worth less than today) and easier to swallow year to year. It'd be no fun to pay him $15M a year for 7 years, but it's not a huge amount per year. And it might lower the price in terms of prospects.
