The No. 13-ranked Michigan Wolverines entered Saturday's matchup against rival Michigan State as heavy, heavy favorites.
But the Spartans and alum Draymond Green got the last laugh.
Michigan State went into Ann Arbor and upset Michigan, 27-24, and the Warriors forward let Michigan legend Charles Woodson hear about it on Twitter after the game.
Woodson, the former Raiders icon, now works as an analyst for Fox Sports. Prior to Saturday's game, Green made an appearance on the pregame show, and that's where the trash talk started.
When Woodson asked Green about Michigan pulling back a scholarship offer before he committed to Michigan State, that was Draymond's chance to take a shot at Maize and Blue.
"[Former Michigan coach] John Beilein was heartbroken when I decided to go to Michigan State," Green said. "I think Michigan State is just a much better place."
Earlier this year, Green appeared on the "All The Smoke" podcast with former Warriors Matt Barnes and Stephen Jackson. He was asked about his recruitment and explained why he eventually picked Michigan State over Michigan (H/T Detroit Free Press).
"So I go down there ... I'm busting they ass," Green said. "I'm talking (expletive), I'm busting they ass, and nobody is talking back.
"And at the time, Manny Fresh (Manny Harris) was there, Petey (DeShawn Sims) was there. Petey ain't a big talker, Petey from Detroit. Manny (is) not a talker. ... And then like the rest, Kelvin Grady, but there were a lot of squares on the team. ...
"But I'll go to Michigan State, and I'm talking (expletive), and Travis Walton is trying to fight me and everybody is trying to fight. And that's me. ... That's more me that me talking and everybody looking at me.
"And so, Michigan State just felt more at home for me. But had Michigan just left my ass at home and not (expletive) called me on that Monday, I would have went to Michigan."
History might be completely different if Green had gone to Ann Arbor instead of East Lansing.
For now, though, Green and his Spartan Dawgs have bragging rights over Woodson and the Wolverines.
