In 2006, Jay-Z released a song where he rapped, “30′s the new 20″ despite the fact that he was way closer to 40 than 30. People laughed at him for being out of touch — an old man in a young man’s game, rapping about how being old was really a cool new way of being young. As Jay himself would has said, “We don’t believe you, you need more people.” After all, there aren’t a lot of big-time 40-year-old rappers. Just ask KRS-One and Chuck D.

Similarly, there aren’t a lot of successful 42-year-old basketball players, unless you’re a huge Kevin Willis fan. But that doesn’t matter to the Dallas Mavericks who are thisclose to agreeing to pay Jason Kidd $3 million a year to play basketball for the next three season. From ESPN:

Jason Kidd appears prepared to end his career where he started it — with the Dallas Mavericks.

The 39-year-old is closing in on a multiyear deal, a source close to the situation said. The source said the deal is not completed, but barring any snags, Kidd will close out his career alongside Dirk Nowitzki.

Sources with knowledge of the deal specifics told ESPN.com’s Marc Stein that Kidd’s contract will be a three-year deal worth $9 million, taking him to age 42 if he plays it all the way out.

Yiiiiikes. Unless the Mavericks can find a Kanye figure to rejuvenate Jason Kidd, this is Bad News Bears. A 3-year contract for Jason Kidd? That’s like signing up for a 30-year mortgage when you’re 65 or some other age-based analogy where you are making an ill-advised investment because one of the involved parties is super old. Might as well just bring John Stockton back from the grave.

But who knows. Maybe Jason Kidd will literally find the Fountain of Youth, Ponce de Léon style, and bounce back from the worst season of his career. And then follow that up by keeping the Fountain a secret so he can continue to drink from it for the next two seasons. Barring that, this seems like way too long of a contract for someone so old who is probably best suited as a backup at this point in his career, unless there is some sort of special Social Security dispensation we’re not aware of. If that’s the case, great move.

UPDATE: Haha, nope — Jason Kidd is going to be a Knick now. Weird.
