Saturday was no exception.
James and Green placed a bet prior to Michigan State's 17-14 victory over Ohio State. Green, who attended Michigan State, sided with the Spartans, while James took his home state, Ohio.
The wager appears to be a shipment of fine wine.
"I'm calling out LeBron," Green said in a Friday video post. "Big buckeye fan. I know how you hold it down for his Buckeyes. You know, Spartan dog through and through, Buckeye through and through. There has got to be a wager or something so holler at me LeBron. We gotcha all. Spartan dogs to the core. We here."
Green posted another video after the game.
"Bron you will be getting an address. Need that vino on deck. Hold it down. You aint in wine country, but you know the spots. I need that ASAP."
