Both guys seemed like great coaches, great men, and great recruiters. Cahoon helped Hoffman produce his whopping numbers, and developed unknowns like Ridley into decent threats. The dropsy-issues of the Higgins/Anae era largely disappeared under him. And the 2013 WR class (Tanner Shipley, Michael Davis, Talon Shumway, Inoke Lotulelei, Garrett England, Faimafili Moroni Laulu-Pututau) was one of BYU's best ever.
DuPaix helped recruit Jamaal Williams, and was helping him because a threat to be BYU's all-time rusher. This, behind an absolutely TERRIBLE offensive line with a bad offensive coordinator making the play-calls. He was also a stud recruiter and a positive voice on twitter as well, a high-energy guy.
We will see if BYU loses more recruits now. And if the offense is worse next year.
With all that Doman has cost BYU (wins, coaches, etc.) there's no way he should be allowed to remain on staff. If you're Anae and you left BYU because of coaching disagreements and you want to clean house, than go ahead and clean the ENTIRE house.
QB/WR/TE coaches yet to be named. Steve Clark, Paul Peterson, Max Hall have interviewed. Names like Ty Detmer (bad idea), JaBeck, and Chad Lewis will be tossed around until official announcements as well.
