When has a team retained for 5 additional seasons, nevermind as a third team?
Considering Jones' remaining salary, that third team will take on a total of roughly $4,5 million in real dollars by retaining $1 million of his $9,5 million AAV (10,5%). $41 million in his remaining 5 years + however much it will be of his $12,5 million $$$ this year.
$4,5 million might not be a 1st on its own, but it could be 2nd's, or maybe a Gulyayev, if that team likes him.
Getting a third team to retain on his contract is completely unrealistic, borderline delusional, imo.
