Back when he was the WRs coach, he brought in arguably the most talented top to bottom receiving corps in BYU history, several as transfers, before the portal was even a thing (Matthews, Kurtz, Leslie, Blackmon, Juergens, Houk, Pearson). Obviously Fesi is doing a great job, but I don't think it would hurt to have Holliday on the staff in some capacity especially now with the portal.
