Fred and Jamie went on KXNO to refute it. Fred says (paraphrasing), “I talked to Travis earlier this week and told him it wasn’t true and not to run the story.” But in the article, it says “Hoiberg wasn’t available for comment.”
Reading between the lines: Hoiberg was almost certainly one of the anonymous sources. He had some peeves, and was trying to shift some of the heat he was feeling to Pollard. When it blew up, he walked it back.
The salary complaint was that he signed a 10-year contract and JP used the average to say he was in the top X of coaches in the Big 12 when his actual salary for the year was 8th or 9th in conference.
