But is it though? With the league constantly changing it's rules on CBA and expanding the "supermax" it's gets evidently more desirable to sign your contract extension later. Just look at Jokic and Jaylen Brown. Just a year ago in 2022, Jokers supermax extension was still 270mil for 5yr. Then one year later...boom! jaylen browns supermax with the Celtics became 304mil for 5 yrs. That's basically one whole year worth of extra earning. Joker sorta screwed himself by signing that deal one year earlier.
Fair point, but it's hard to imagine that sort of exponential growth in the AAV of a supermax continuing in perpetuity, and/or being impossible for agents to figure out and provide some guidance on when to sign, how long to sign for, etc.
But even in your Jokic scenario - that's still an AAV of $54m per year. If we look at Anthony Edwards (better comp as a recent young star in the first year of his max deal), I think he's making $42m this year. Coop dogg would have to make just insane (read: impossible) NIL money to justify 1) the injury risk of derailing his NBA career and 2) offset the ~$25m in "lost money" between the last year of his rookie deal and the first year of his second (presumably max) contract.
