“Show me a good loser and I’ll show you a loser” is a famous sports saying, used in many sports. ‘Show me a good and gracious loser and I’ll show you a failure” is often credited to Notre Dame football coach Knute Rockne (1888-1931), but that hasn’t been found in print. A 1931 article just after Rockne’s death quoted him as having said, “Be a good loser, don’t beef. But don’t lose.” “‘Show me a good loser and I will show you a failure” was credited to Rockne in 1943.
 
University of Illinois football coach Robert Zuppke spoke in December 1929 about how he disliked the “good loser,” saying “Show me a team of singers about a defeat and I’ll show you a team of punks.” “Show me a good loser and I’ll show you an idiot” was said by the actor Paul Gilbert (1918-1975) in 1956. “Show me somebody who likes to lose and I’ll show you an idiot” was said by the baseball manager Leo Durocher (1905-1991) by at least 1967.
 
“Show me a good loser and I’ll show you a loser” appeared at least twice in print in 1963, said by football player Frankie Albert (1920-2002) and basketball coach Red Auerbach (1917-2006).
   
“Show me a good loser and I’ll show you a man who is playing golf with his boss” is a joke variation that has been popular since the 1980s.

Singing of Defeat.
Robert Zuppke, who directs the football destines of the University of Illinois and usually manages to direct the team to a pretty high spot, dislikes among other things the “good loser.” Zuppke has been the speaker at several football banquets lately, an some of the views he expresses are interesting enough.

“Show me a team of singers about a defeat and I’ll show you a team of punks,” says he. “I detest a good loser. I want bad losers. When my men get licked I want them to be so cut up and to worry so much they’ll make up their minds never to have that terrible feeling again.
 
12 December 1930, Oakland (CA) Tribune, “Just Folks” by Edgar A. Guest, pg. 56, col. 5:
COACH YOST DISCUSSES A GOOD LOSER
Said the gray old coach to me: “Once I heard a fellow say,
The good loser is a sham, think about it as you may.
There is not a man on earth who can wear a cheerful grin
When he has to lose a fight that he really wants to win.
That is merely idle talk, every loss is hard to bear,
And I wouldn’t give a dime for the chap who doesn’t care.”

One of Knute’s select sayings was:
 
“Be a good loser, don’t beef. But don’t lose.”

“Be a good loser but don’t lose,” said Rockne.

It can be presumed that it will be plenty, for these fellows are strictly Rockne men and Rockne despised good losers.
 
‘Show me a good loser,” he used to say, “and I will show you a failure.”
 
31 January 1946, Oakland (CA) Tribune, “On the Level” by Lee Dunbar, pg. 16, col. 1:
Reader Curran says Clint Evans is a poor loser. That statement is absolutely true. And, oddly enough, it is this very quality I most admire in him. Never, since I’ve been old enough to reason for myself have I had a particle of respect for the so-called “good loser.” Show me a good loser and I’ll show you a guy without an ounce of competitive spirit in his makeup. And a man without competitive spirit has no place in athletics.

Readers (Bless ‘em) Write
“I enjoy your Sports Mirror very much, it’s my most interesting reading. However, your statement in the morning paper caused me to disagree with you. You said, “Show me a coach who always appears the perfect gentleman in the heat of battle and I’ll show you a consistent loser.”

As Asa Mullington, three times world champion, points out in his “Tiddlywinks As I See It,” “crossed legs and titles walk hand in hand. Show me a comfortable tiddlywinker and I’ll show you a loser.”
