Hence 5 guys with over 500 yds this year. Yes they lose 3 of those, but get Trinnaman, and have MLP, Dye, Weeks, Davis, etc, etc. Heck, they might even land Zach Farrar who could contribute well as a freshman. Point is BYU going forward will have much better depth and not have "Hoffman and nobody else" type situations.
Mathews had his issues too and he fixed a few for his senior year. I'm sure another year will only help Kurtz as well.
