I have my copy of Adoph Rupp's biography written by Russell Rice that was authorized br Rupp himself, KENTUCKY'S BASKETBALL BARON that discusses Rupp' "1923 Champion season" at Kansas. This would have only been reference to a Helms Foundation Championship. Rupp believed it was a "championship". All good Wildcat fans should have read this book in grade school. I don't carry my book on the road (travelling for business) or I would have quoted page numbers for you.
This book approved by Coach Rupp, the UK media guide and Buck's shows that at one time Rupp and UK embraced the Helms Foundation Championship. It is clear that your fan base and the Duke fan base do not embrace it today. I understand why Duke fans believe that. And, I am okay that BBN agrees with the Dukies.
Maybe I'm missing something but I checked Russell Rice's book (Adolph Rupp: Kentucky's Basketball Baron) in the chapter about Rupp's time at Kansas and didn't see any quote from Rupp concerning what he thought about the Helms title being bestowed on those teams he played on at Kansas.
The only thing I did see that was potentially relevant is the following (from Page 11 of the Chapter entitled 'Jayhawker'):
"The Jayhawkers, undefeated in collegiate play, claimed the nation's championship. [Paul] Endacott and Charlie Black were named All-America, and Endacott was named Player of the Year by the Helms Foundation."
A couple of things about this:
1.) None of this was a direct quote from Rupp
2.) the passage doesn't directly say whether the claim of 'the nation's championship' was attributed to Helms (which would have occurred in 1943) or more probably it was a claim Jayhawk boosters made at the time, which was not uncommon to occur although as Rupp acknowledged over 10 years later in his quote such a claim during that era was ungrounded.
3.) Rice is a great historian but his comments about All-Americans are frankly a little sloppy in this case. I don't know that All-Americans were named until College Humor and Christy Walsh started in 1929, followed a few years later in 1932 by Converse. Assuming that's the case, any All-American honors that Endacott and Black received would have been retroactive in nature which was not made clear by Rice (although that's a common mistake that's made).
4.) As has been mentioned already this book was in no way authorized by Rupp, who had been dead for at least 15 years when Rice wrote this. I think Rice recognized (which he hints at in his forward) that he really was the most qualified person to write a biography of Rupp.
5.) there is no index in this book so perhaps the Helms was mentioned elsewhere.
Having said all that, I did also check Rice's book "Big Blue Machine" and did indeed find a quote from Rupp where he states (in the Chapter entitled 'Time Out: Adolph Rupp):
"I played on two national championship teams at Kansas. I was a member of what Phog called his 'meatpackers,' which meant that we got in the game when things were pretty settled, one way or the other. I had the misfortune of playing behind two fine All-Americans, Paul Endacott and Charlie Black. When we had a class reunion many year later and were lining up for a picture, I told Paul, 'Let me hold that ball. I never got a chance to hold it while I was playing.'"
Was Rupp referring to the Helms? Probably he was. Does it fundamentally change anything about this current debate ? Not really IMO.
