Purdue has long held an edge in its rivalry with Indiana on the football field.

From 1997-2012, the Boilermakers won 13 of the 16 matchups for the Old Oaken Bucket. But since then, the series has evened up a bit; Indiana is 5-3 in the last 8 games, including a 4-game winning streak from 2013-16.

Overall, Purdue leads 75-42-6, including a 61-32-3 run since the traveling trophy — the Bucket — was introduced in 1925. Following, let’s take a deeper look into the rivalry, specifically the 10 biggest upsets in Purdue vs. Indiana history:

Indiana 19, No. 3 Purdue 14

Nov. 25, 1967 • Seventeenth Street Football Stadium (Memorial Stadium)

In 1967, Purdue was considered the class of the Big Ten, but the Boilermakers weren’t eligible for a trip to the Rose Bowl because in those days teams were ineligible from going to the “The Granddaddy of Them All” in consecutive seasons. It left the door open for Indiana, which was enjoying a fine season as well, but was coming into the rivalry game after an ugly loss to Minnesota a week earlier that kept the Hoosiers from clinching the bowl trip.

Instead, IU would need to upend Leroy Keyes and the Boilermakers to earn a trip to Pasadena. Indiana took control in the 2nd half, thanks in large part to a long Terry Cole touchdown run that put the hosts up 19-7. The Boilermakers clawed back to within a possession, but turnovers were a gigantic problem, as Purdue fumbled 3 times. The last was the clincher for the Hoosiers, when linebacker Ken Kaczmarek hit Boilermakers fullback Perry Williams near the goal line in the 4th quarter, causing him to fumble and preventing Purdue from taking the lead.

With the win, the Hoosiers earned their 1st trip to the Rose Bowl.

Indiana 38, Purdue 31

Nov. 20, 1971 • Seventeenth Street Football Stadium (Memorial Stadium)

No one is going to write a book about the 1971 seasons for Purdue and Indiana, as neither team had made much noise in the Big Ten. The Hoosiers came into the Bucket game with only 1 Big Ten win, although it had come the week prior, when IU upset Iowa in Iowa City.

Indiana made it 2 in a row when Purdue, which had seen its 3-game Big Ten winning streak in October (Iowa, Minnesota and Northwestern) be followed by 4 consecutive losses, came calling. It was an ugly one for the Boilermakers, who turned the ball over 4 times, each one leading to an Indiana touchdown. The win marked a bit of a revival for Coach John Pont’s program, which had reached the zenith a few seasons earlier with the Rose Bowl trip, but it didn’t last. He was gone 2 seasons later.

Indiana 20, Purdue 14

Nov. 20, 1976 • Ross-Ade Stadium

In 1976, Purdue had a chance to finish above .500 for the 1st time under 4th-year coach Alex Agase, but it wasn’t meant to be. Instead, coach Lee Corso brought his Hoosiers into West Lafayette to score an upset over the Boilermakers in what turned out to be Agase’s last game as Purdue’s boss.

Indiana 20, Purdue 17

Nov. 21, 1981 • Memorial Stadium

Indiana didn’t have a ton to play for at the end of ’81, other than pride and a chance to knock the Boilermakers out of the bowl picture. But that was plenty of motivation for Corso’s Hoosiers.

The game was tied before Doug Smith kicked the go-ahead 39-yard field goal with 8:30 left. The Boilermakers had a couple chances late, but both of their drives ended in interceptions. It was the end of a disappointing season for Jim Young’s Boilermakers, who started the season 5-2 only to lose 4 consecutive games, including the Bucket contest.

Purdue 17, Indiana 15

Nov. 22, 1986 • Ross-Ade Stadium

Purdue scored a rare upset in the series — and the 1st of a couple in the 80s — when a 3-win team coached by Leon Burtnett knocked off a bowl-bound Bill Mallory squad to keep the Bucket for a 4th consecutive season. The game sent Burtnett out a winner, after he had been forced to resign a few weeks earlier.

But the man of the day was Rod Woodson. In a game that Burtnett would later call the “greatest game I ever saw one individual play,” according to the Journal & Courier, Woodson finished with 10 tackles, a pass breakup and a forced fumble, plus 93 yards rushing, 67 yards receiving, 2 kickoff returns and 3 punt returns (totaling 76 yards). Woodson, an All-American, played 137 snaps and had 236 all-purpose yards.

But it was a late special teams play that sealed the Boilermakers win. With a minute left, Purdue freshman Scott Schult blocked the potential game-winning 34-yard field goal attempt by Pete Stoyanovich.

Purdue 15, Indiana 14

Nov. 25, 1989 • Memorial Stadium

Indiana had a ton to play for at the end of the 1989 season, needing a victory against Purdue to gain bowl eligibility and give star running back Anthony Thompson a showcase game to pad his already impressive Heisman Trophy résumé. The Boilermakers, meanwhile, had no such incentives, yet Purdue came ready to upset IU in Memorial Stadium.

The Boilermakers were going nowhere under coach Fred Akers, who was in his 2nd-to-last season in West Lafayette. But Purdue picked up Win No. 3 in ’89, eking out a 15-14 victory in Memorial Stadium. It was a particularly disheartening loss for the 2-touchdown-favorite Hoosiers, who saw their bowl hopes end along with the Heisman chances of Thompson, who finished 2nd in voting to Houston quarterback Andre Ware.

Indiana 33, Purdue 16

Nov. 23, 1996 • Ross-Ade Stadium

Neither Purdue nor Indiana had much success in 1996, but the Boilermakers at least built some momentum in the last couple weeks of the season, even after Jim Colletto had become a lame duck coach.

Colletto though maybe he could earn his job back after Purdue upset No. 3 Michigan in Ross-Ade Stadium 2 weeks before the Bucket game, but that wasn’t going to happen. And for the Boilermakers, the end of the Colletto era came with a thud. Bill Mallory’s last IU team came to West Lafayette having lost 8 consecutive games, turning in a 2nd consecutive sub-.500 season.

The Hoosiers dominated, winning their 1st Big Ten game in 2 seasons. Mallory was replaced by Cam Cameron after the season, while Colletto was replaced by Joe Tiller.

Indiana 13, Purdue 7

Nov. 24, 2001 • Memorial Stadium

It might be a surprise to many, especially Purdue fans, but the 2001 game was not, at least by Vegas standards, an upset. But boy did it feel like one.

The Boilermakers had came into the game winners of 4 straight in the series, but in monsoon-like conditions — the game was played in a near-complete downpour in Bloomington — the Hoosiers, who were 3.5-point favorites, seemed better equipped to deal with the inclement conditions. Indiana took an early 13-0 lead, scoring touchdowns on runs by running back Levron Williams and quarterback Antwaan Randle El. The Boilermakers tried to rally in the 2nd half, scoring on a touchdown pass from Kyle Orton, who was making his 1st career start, to John Standeford, but twice their drives were thwarted inside the 20-yard-line, including once when Purdue was stuffed at the 1.

The win helped IU finish with a .500 conference record for the 1st time since 1994.

Indiana 27, Purdue 24

Nov. 17, 2007 • Memorial Stadium

Before the 2007 season, coach Terry Hoeppner promised his Hoosiers would “Play 13,” signifying they’d advance to a bowl game by winning at least 6 regular-season games. Unfortunately, the much-loved coach wasn’t there to see it through, after dying from complications of brain cancer prior to the season.

But his team came through. Austin Starr’s 49-yard field goal with 30 seconds left was the difference — Purdue was a narrow 1-point favorite in Memorial Stadium — as IU got its coveted 6th win of the season and qualified for a bowl game for the 1st time in 14 years.

It was a heck of an effort by Bill Lynch, who had taken over as coach, and an offense led by quarterback Kellen Lewis and wide receiver James Hardy.

Indiana 34, Purdue 31

Nov. 27, 2010 • Ross-Ade Stadium

With an overtime victory in Ross-Ade Stadium, the Hoosiers ended a few streaks: 12 consecutive losses in the Big Ten and a 15-game losing skid away from Memorial Stadium. And they managed to win a Big Ten game, avoiding a winless conference season for the 1st time since 1995.

It was also IU’s 1st win in West Lafayette since 1996.

Purdue wasn’t great in ’10 — it finished with only 4 victories — but the Boilermakers were a 4-point favorite. However, the Hoosiers got 2 late field goals from Mitch Ewald to secure the victory, the 1st to send the game to overtime, then the 2nd to win it.
