How about the “cancel-the-team-banquet” controversy?
Or do you focus on big victories by the Boilers and the Hoosiers over the years?
Here are a few facts as the teams brace for Saturday's 200th meeting. They started playing in 1901 and Purdue dominated the early series. IU swept the Boilers for the first time in 1940, the year it won its first of five national championships.
The rivalry peaked in the 1980s and '90s under Indiana coach Bob Knight and Purdue coach Gene Keady. They were both bigger-than-life men who coached hard, won often and never backed down. They combined for 16 Big Ten titles and 13 conference coach of the year awards.
Both coaches respected each other, but both wanted to beat each other in the worst way.
In other words, things got heated.
For instance, during the early 1990s, a Knight locker room tirade was secretly recorded by a player or manager. It came during a bad practice leading up to a Purdue game, and it included the famous line, “I'm BLEEPING tired of losing to Purdue!” Other lines included, “You guys will BLEEPING run till you can't eat supper!” and “I'll run your BLEEPS into the BLEEPING ground. You'll think last night (in practice) was a BLEEPING picnic!”
Knight let his players known, in explicit terms, how bad the next “four BLEEPING days” would be if they lost.
Oh, yes. IU won.
Anyway, Purdue leads the overall series 112-87, but IU has won the last three meetings, all by double digits, including last month's 37-point blowout at Mackey Arena.
Here's a look at 10 of the series' most memorable games:
1) THE CHAIR: What Knight perceived as season-long bad officiating peaked in this Feb. 23, 1985, classic at Assembly Hall. Five minutes into the game, Purdue and IU battled for a loose ball. The Hoosiers' Daryl Thomas was called for a foul.
Knight shouted that it should have been a jump ball. When he wouldn't stop yelling, he was hit with a technical foul. Purdue's Steve Reid went to the line to shoot the free throws. A furious Knight grabbed a chair from the IU bench and threw it across the floor in front of Reid.
Knight was ejected, but he left the court to a standing ovation. Purdue went on to win, 72-63.
Knight apologized but was given a one-game suspension by the Big Ten. Over the years, Knight has joked that he didn't throw the chair in anger but because an old lady sitting on the other side of the court shouted that she needed a chair to sit, so he threw her one.
2) THE BLOWN LEAD: It was March 1992 and IU blew a 10-point lead at Purdue in the final minutes and lost 61-59. A month earlier at Assembly Hall, the Hoosiers had crushed the Boilers 106-65. It was the regular-season finale and cost them a share of the Big Ten championship with Ohio State. They went from a No. 1 seed in Cincinnati to a No. 2 seed in Boise, Idaho, for the NCAA Tournament.
Knight was furious. The next day he caused an uproar by canceling the team banquet. When organizers protested, he said the timing had nothing to do with the loss (nobody believed him) and, besides, it was a lousy banquet.
Knight responded to all the criticism with his famous “cerebral reversal” NCAA news conferences. In his thinking, he had to talk to the media, but he didn't have to say anything worthwhile. So he filibustered his way through with fictitious talk of Chinese water torture and team camp-outs. He said he made his players sleep in the cold in parking lots, turning fire hoses on them every couple of hours. He said he stuck their feet in buckets of cold water, chained them, starved and whipped them.
At one point, he brought out a whip his son, Patrick, had given him. He dipped the tip in water because, he said, that improved its effectiveness.
The result — IU won four straight games and reached the Final Four before losing to Duke in the semifinals.
3) NCAA TOURNEY DRAMA: The teams have met just once in the NCAA tourney. That happened March 13, 1980, in the Sweet 16 in Lexington, Ky.
Purdue and IU had split their regular-season meetings. IU won 69-58 at Assembly Hall. Purdue won 56-51 at Mackey Arena.
The Hoosiers had the higher ranking (No. 1 to No. 20), the higher NCAA tourney seed (No. 2 to No. 6) and one of America's best players in freshman guard Isiah Thomas. Thomas scored 30 points, but the Boilers controlled the game behind 20 points each from Drake Morris and Keith Edmonson, and won 76-69.
Purdue advanced to the Final Four in Indianapolis before losing to UCLA.
4) DOUBLE DRAMA: It was 1987 and both teams were powerhouses. They met for the first time at Assembly Hall on Jan. 31. Both were tied at No. 4 in the AP poll. IU won this one, 88-77. In the rematch a month later at Mackey Arena, with both teams still ranked in the top 10, Purdue won 75-64 behind Troy Lewis' 19 points.
The Hoosiers lost a few days later at Illinois, 69-67, before going on a roll that culminated with their last national championship.
5) BUZZER-BEATER: Indiana's A.J. Guyton seemed to have forced a second overtime against Purdue on Feb. 18, 1997. His late three-pointer tied the score at 87-87 in Assembly Hall. But the Boilers' Chad Austin hit a jumper with less than a second remaining to give the visitors the 89-87 victory.
Brian Cardinal led Purdue with 25 points. Austin added 18.
It was the 400th win of Gene Keady's career.
6) DUEL IN THE DOME: Because of Big Ten schedule challenges, IU and Purdue were set to meet just once in the 2001-2002 and 2002-2003 seasons. School officials organized a non-conference game at the Indianapolis RCA Dome for Dec. 14, 2002. More than 32,000 people showed up to watch.
The No. 6 Hoosiers had been the 2002 national runner-up. They were 7-0 and looking like a national contender. Purdue was 4-1 and on its way to another NCAA tourney berth.
IU held on to win a back-and-forth game 66-63 behind forward Jeff Newton's 16 points, including nine in the final three minutes.
The Hoosiers lost their next game, to Kentucky. Coach Mike Davis ran onto the court near the end of the game and was ejected. He later was suspended for a game. IU went 13-13 the rest of the season.
7) THE SEAT OF HIS PANTS: It was a nail-biter of a game Feb. 28, 1948, so it had to end that way. With five seconds left, Purdue's Howie Williams dived under the basket to grab a loose ball. He was sitting when he tossed in the game winner in the Boilers' 51-49 victory.
8) KEADY FAREWELL: Purdue's Gene Keady was set to wrap up an outstanding career in 2005. His Boilers were struggling and would go on to win just seven games.
But on this Jan. 15 night, they had a chance against their biggest rival at Mackey Arena.
They led early. IU stormed back. David Teague scored with 25 seconds left to give Purdue a 55-52 lead. The Hoosiers' Marshall Strickland responded with a three-pointer to force overtime.
With less than a second remaining in the first overtime, the Boilers' Andrew Ford was called for a foul and Strickland made both free throws to give IU a 63-61 lead. Purdue's length-of-the-floor pass went to Carl Landy, who made a layup and was fouled. He missed the free throw to send the game into a second overtime.
Teague's three-pointer with 5.7 seconds left in the second overtime cut IU's lead to 74-73. The Hoosiers' Bracey Wright was fouled and made one free throw. Brandon McKnight's desperation shot missed. IU had survived.
This remains the only double-overtime game in series history.
9) NIT TITLE: It was March 21, 1979, and the teams were looking for bragging rights in the NIT championship game. Both teams had split regular-season meetings. The Hoosiers won 63-54 in Bloomington. The Boilers won 55-48 at Mackey Arena.
They each won three NIT games to reach the championship in New York City. IU won 53-52.
10) THE DONKEY SHOW: IU and Purdue split a pair of hotly contested meetings in 1981. The Hoosiers won in Bloomington 69-61. The Boilers won in West Lafayette 68-66.
The games were physical and, in one, there was an alleged “sucker punch” between IU's Isiah Thomas and Purdue's Roosevelt Barnes. Knight used his TV show to try to prove Barnes provoked the incident.
Knight then stirred the masses by bringing a donkey on the show wearing a Purdue cap. Knight said the donkey's name was Jack and “I'll let you figure out his last name.” He said the donkey was a substitute for Purdue Athletic Director George King, who declined to appear on the show. Knight said the donkey would “probably express the same ideas (as King)” and would be “symbolic of Purdue fans.”
The Hoosiers would go on to win the national championship.
