 recounted the following story:

"His life at the University of Alabama was made miserable at one point when he was unwilling to pass some members of the football team. He had them over to his house and not only patiently tutored them but even watered down the tests somewhat, but they still could not pass. He was told by the administration that the team was Rose Bowl material and that he had to pass them. When he refused, the administration put the low-scoring students in the hands of a more malleable faculty member, with the result that the team kept on winning."http://www.nap.edu/readingroom/books/biomems/bkaufmann.html

The Carnegie Institution at the Cold Spring Harbor had no football team.
