Nothing's guaranteed, so knock on wood, but this is as close as you'll get with something this important.
Thanks to the timing of the Dodgers' ownership transition, count on Clayton Kershaw remaining a Dodger for years and years and years — until at least the end of the decade or close to it.
Matt Kemp might get away (though hopefully not) because the next Dodger owner might not be in place in time to lock him up before Opening Day, and might not outbid other teams if Kemp becomes a free agent.
But there's no way new ownership, who will be properly vetted by the industry, backed by the next Dodger local TV deal and fully conscious of the import of retaining the closest the Dodgers have come in 45 years to reinventing Sandy Koufax, will not sign Kershaw to a long-term deal before November 2014, when Kershaw can become a free agent. He'll get a long-term deal, whatever it takes.
Kershaw is yours.
Update: Kershaw won the MLB Players Choice Award for outstanding National League pitcher, while Matt Kemp was voted NL outstanding player.
