The assistant coaches Fueger, Robinson, and Fennell. It would be nice to get Jax back, but I think losing one or more of those coaches coach have a bigger impact on next year. I say this only because it seems like it was the coaching that was able to find the right system for this team to maximize their abilities over the course of the whole season and barring something miraculous (landing a transfer or dramatic offseason skill development) BYU will need to rely on the right system to be successful next year rather than a few superstar players who can just outperform their competition each game.
