That’s what he should have said. That is not what he did say, unintentionally I’m sure.
Here’s Gurley’s contract:
Note how it is broken out annually - it does not add up to ~$15M/yr every year. It is a $4.2/yr guaranteed each year ($21M paid up front but spread over 5 years [and a carry over last year from the previous signing bonus]), some large roster bonuses in 2020 and 2021 that also qualify as guaranteed money, and $950k annual salary last year, $5M annual salary this year, $5.5M annual salary next year, and $4M annual salary in 2021.
Gurley pocketed about $22M last year ($21M guaranteed signing for the new extension and $950K salary). He’ll make $5M this year - annual salary only. He can make $13.1M next year with the roster bonus and $5M annual salary. He can make $9M the following year with the $5M roster bonus and $4M salary, and then there is an option year in 2022.
See how that doesn’t add up to anything like $15M annual salary? That gets him his high guarantees but also protects the team in the event that he were not able to play after this year for some reason. That’s cap management.
