Well, Malmo, Chris Lear interviewed El G and his coach, Abdelkada Kada, in the book on Alan Webb, Sub 4:00, see pages 211-214. Lear writes that El G's coach said, "the American college system must be dismissed as a developmental ground for world-class milers. For sprinters, he said, it's okay. But for milers, he believes the demands of racing for three seasons are too great. He feels that collegiate coaches too often compromise the training of their milers in favor of short-term gain-a conference title, and invitational title, and so on. He stressed the need for a limited racing schedule, with no more than three or four races indoors and six races outdoors." Then he wrote El G "agreed with his coach, dismissing the collegiate system as 'not good at all' for developing middle-distance talent."
Then in Running with the Buffaloes, read p. 118-119, Mark Wetmore's interpretation of Haille G.'s quote on the Golden League, as "good, but not for distance runners. There are too many races in too short a time." So he applied that concept to a major theme of book, uninterrupted training coupled with limited racing. He discusses that principle all through the book.
So Haille did not directly comment on college runners, but the point is applicable, especially through Wetmore's comments and coaching methodology. El G and his coach directly commented on the issue.
You need me to look anything else for you Malmo?
