or at least I found the source of the information. I was sitting on the can reading a football program (TMI, I know)(UCLA vs. Utah, 2022). The article on D. Foster states he was a volunteer assistant while Perk was her and "Foster was instrumental in the development of Paul Perkins." Take it for what you will. At least I found where I got that notion.
Given the source, and the timing of my "research," you can't say I'm FOS. Quite the opposite, actually.
