I think the point he was making is that if the coach puts a winning product on the court, and better yet an exciting winning product, raising money for the program becomes easier. If the coach keeps rolling out boring mediocre teams that lose to USF, Tulane and Tulsa, the AD's job becomes much harder when he asks for money for the program.
Donnie Jones was likely working with a similar budget and brought in B.J. Taylor, Tacko Fall, A.J. Davis, Brandon Goodwin, Matt Williams, and others. You can't just use the excuse of budget and give up. There has to be a symbiotic relationship between the AD and Coach with both doing their part.
