October 20, 2018 is a day that a lot of Buckeye fans won't forget for a long time.
The Buckeyes were coming into the game undefeated and No. 2 in the country into what some labeled as a "trap game," especially after the Buckeyes were curb-stomped in a similar situation against Iowa the year prior.
It turned out to be exactly that. Rondale Moore caught 12 passes for 170 yards and two touchdowns, while Purdue running back D.J. Knox scored three more times, and the Boilermakers obliterated the Buckeyes 49-20.
The game would be the Buckeyes sole blemish in what turned out to be Urban Meyer's last season at the helm, as Ohio State was left out of the College Football Playoff and instead went to the Rose Bowl, where they defeated Washington.
Earlier that year, in February, a Buckeye basketball team ranked No. 14 in the country (and by all counts overachieving) went into Mackey Arena as major underdogs against Isaac Haas, Carsen Edwards, and the Boilermakers, who were No. 3 at the time.
Ohio State pulled off a stunning upset, led by Keita Bates-Diop, the future Big Ten Player of the Year who had a put-back of a Jae'Sean Tate miss with 2.8 seconds left, giving the Buckeyes a monumental win.
The Buckeyes were hoping for a similar result last year in Mackey, but this time the arena and the Boilermakers won in an 86-51 blowout. The Boilermakers came in to the game No. 14 and Ohio State was unranked. This game gave Purdue sole possession of first place in the Big Ten (at the time).
As we enter Saturday's tipoff, with neither team ranked, the stakes will not be nearly as high as they have been in the past. But you can bet it will probably be a good one and you can bet there is going to be one really frustrated fan base after it is over.
