2019 his 2nd contract kicks in. That's the 5y/81M.
Saying he got 16 M a year (which is what people say) doesn't make sense if you fold the separate rookie contract into it. Saying he got 16 M a year means the 5 year contract is separate and different from the rookie contract.
And that's how it's reported. Just a few examples:
